English Language Basics: Parts of Speech




Introduction


In the English language, words can be considered as the smallest elements that have distinctive meanings. It is these words that form every other grammatical structure- be it a phrase, a clause or a full sentence.


Parts of speech therefore is a category to which a word is assigned in accordance with its syntactic functions in any grammatical context.


In its simplest form, parts of speech can be defined as the word class components of our grammatical structure, be it written or spoken. 


In English Language, it simply refers to the basic components of our expressed thoughts and communications either orally communicated or in written form.

The best way to understand this is by considering parts of the body, motor parts etc. As the body is made up of different component parts, without which there is no body, so without these parts that make up our grammar, there is no grammar.


Based on their contextual uses and functions, words are categorized into 8 major parts, namely;



*** Noun
*** Pronoun
*** Adjective
*** Verb
*** Adverb
*** Preposition
*** Conjunction
*** Interjection/Exclamation

The implication here is: whenever a speech is made, the words that make up that speech are derived from any of the foregoing eight parts of speech.

For example, someone said: "My mother is a very beautiful woman."

The above speech is made up of seven words. Now let’s see the family of words each of them belongs to based on the context of the statement:

**’My’ here is from the family of adjective.

** ‘mother’ is from the family of noun.

** ‘is’ is from the family of verb.

** ‘a’ is from the family of adjective (though it belongs to a special class, called ‘articles’).

** ‘very’ is from the family of adverb.

** ‘beautiful’ is from the family of adjective.

** ‘woman’ is from the family of noun.


This is just an idea of what parts of speech is all about.

We are now going to look at each of these parts of speech one by one.



NOUN

Noun is simply defined as a naming word. Conventionally, we define a noun as a name of persons, animals, places, things and ideas. 

Meanwhile, beyond this definition, students can identify a noun in any grammatical context based on the questions it answers. A noun answers the question, ‘what?’ or ‘who?’.

Examples of nouns include Smith, Adewumi, Bassey, Chidimma, Ibrahim, goat, dog, Lagos, London, Japan, chair, laptop, intelligence, beauty, teacher etc.


Examples in sentences

1.     Ujunwa is a pretty girl.
2.     Our teacher flogged John for bullying.
3.     I prefer spending money for the laptop to receiving the free gift.



PRONOUN

Pronoun is simply defined as a word used instead of a noun. This simply means that instead of repeatedly using a particular in a context, a pronoun can come in to avoid monotonous use of words.

For example, let’s look at this grammatical structure:

Franklin was not in school yesterday and when Franklin was asked why Franklin was absent; Franklin confessed that Franklin slept very late the previous night because Franklin was watching a movie deep into the night, which made Franklin to wake up very late the following morning that Franklin could not make it to school”. 

Guess you enjoyed the repeated use of the noun, ‘Franklin!

I am sure your answer is a resounding ‘NO’!

Now try to replace each of the word, ‘Franklin’ (exception to the first one) with the pronoun, ‘he’ or ‘him’ (where applicable) and see how meaningful it will appear.

Franklin was not in school yesterday and when he was asked why he was absent; he confessed that he slept very late the previous night because he was watching a movie deep into the night, which made him to wake up very late the following morning that he could not make it to school”. 

The term, ‘pronoun’ simply means ‘for noun’. Anywhere you see it, it is actually representing a noun. Examples include I, he, she, they, us, her, it, our, theirs etc.

Example in sentences

1.     He is an American pilot.
2.     She was asked to give them the books.
3.     Do you know these books are mine?



ADJECTIVE

Adjectives are simply defined as words used to describe a noun or a pronoun. One other way to identify an adjective in a grammatical context is the question it answers. It answers the question, ‘which?’.

Examples of adjective include good, brilliant, wicked, ugly, sweet, young, red, big, magnificent, industrious, fast, slow, harmful, faithful, Nigerian etc.

Examples in sentences

1.     Accra is a big city.
2.     My father bought me a brown sandal yesterday.
3.     Neymar is a Brazilian footballer.



VERB

Verbs are simply defined as action words or doing words. Any word in a grammatical context that indicates action or state is basically a verb. Examples include jumping, clap, look, fried, applauded, cook, write, disturb, hear etc.

Examples in sentences

1.     Ada came to our house yesterday.
2.     We are writing continuous assessment test now.
3.     I will preach in our church this evening.



ADVERB

Adverbs are simply defined as words that modify a verb. In practice, adverbs also modify adjectives and fellow adverbs. It describes the how, the when, the where, the condition, the frequency etc of a verb action in a grammatical context. We have different types of adverb, which is treated extensively under the topic: ADVERBS.

Examples of adverb include slowly, angrily, yesterday, now, today, tomorrow etc.

Examples in sentences

1.     The Headmistress shouted angrily at the teachers for their misdemeanor.
2.     My uncle travelled to Abuja yesterday.
3.     Mrs Jide is a very good chef.



PREPOSITION

Prepositions are words placed before nouns or pronouns to show the relationship between one side of a grammatical structure and the other. It is called pre-position, because it usually takes position before the noun or pronoun it is linking up.

Examples include on, in, under, from, for, of, with, through, over, along etc.

Examples in sentences

1.     The cat is under the table.
2.     The bird flew through the window.
3.     I received the letter from the post master.



CONJUCTION

Conjunctions are simply defined as linking or joining words as they are used to join words, phrases and clauses together. The term con-junction connotes creating a junction between two sides of a grammatical structure. Examples include: and, but, yet, because, if, before, though, unless, except etc.

Examples in sentences

1.     Chris and Coleman are good friends.
2.     He failed the test because he did not prepare for it.
3.     I will help you if you promise to keep the secret.



INTERJECTION/EXCLAMATION

Exclamations are words used to indicate outburst of emotion, such as anger, surprise, command etc. They are usually indicated with the exclamation mark,’!’. Examples include: wow!, hello!, oops!, oh! Etc.

Examples in sentences

1.     Oh! My God!
2.     Wow! What a wonderful performance!
3.     Oops! This is rubbish!

Nutrition: Food Classes and Functions




 Basic Definition

Ø What is food? Food is any nutritious substance that humans and animals eat or drink or that plants absorb in order to maintain life and growth. In other words, food is any substance consumed to provide essential nutrients for man and animals.

Ø What is nutrition? Nutrition is the process of taking in nutrients from the foods we eat. In other words, nutrition is the study of relationship between the food we eat and the composition of the essential nutrients therein. It is these essential nutrients contained in the food we eat that form what is popularly termed, ‘Classes of Food’ or ‘Components of Nutrition’


Classes of Food

The food we eat can be classified into six (6): These classifications are based on their nutritional components.
They are as follows:

*    Carbohydrates

Carbohydrate foods are primary source of energy to the human body. Carbohydrates are made up of sugar, starch and dietary fibres. 

Major Sources of Carbohydrates
1.     Sugar and sugary products: This includes refined sugar, carbonated soft drinks, other industrial products with sugary contents.

2.     Natural starchy foods: This includes yam, cassava foods, cocoyam, rice etc.

3.     Soluble fibre: This includes brown rice, barley, oat, legumes, fruits, nuts etc.

4.     Insoluble fibre: This includes wheat, corn, whole grain bread, cereals, vegetables, fruit skins etc.

Major Functions of Carbohydrates
i.                    Supply of energy to fuel muscle and brain functions;
ii.                  Dietary fibre, which is a component of carbohydrate helps to control blood sugar levels and cholesterol in the blood stream;
iii.                Some carbohydrate sources can as well help to alleviate digestive disorders like constipation, and may also help to prevent colon cancer.


*    Protein
     Proteins are body-building nutrients contained in the food we eat. In practice, protein from food is broken into amino acids by the digestive system, which is then used in the body-building processes.

Major Sources of Protein
1.     Animal products: This includes meat, fish, poultry, egg etc.

2.     Dairy products: This includes milk, cheese etc.

3.     Legumes and seeds: This includes beans, lentils, dried peas etc.

Major Functions of Protein
i.                    Building of muscles and tissues needed for growth and development of children;
ii.                  Repairing of worn-out tissues;
iii.                Important for a healthy immune system as it supports the white blood cell;
iv.               Where carbohydrate is not adequate, protein supplies supplementary energy to the body.

                                                              Fats
     Fats are energy giving nutrients found in the food we eat.

Major Sources of Fat
1.     Saturated fat: This is found mainly in animal-based foods such as meat, milk products, poultry, fish etc. meanwhile, poultry and fish have less saturated fat. Tropical oils such as coconut oil, palm oil and cocoa butter are more or less saturated.

2.     Unsaturated fat: This is mainly found in vegetable oil.

Major Functions of Oil
i.                    Maintenance of skin and hairs;
ii.                  It cushions vital organs;
iii.                It provides insulation;
iv.               It is necessary for the production and absorption of certain vitamins and hormones;
v.                 It is a good source of energy to the body


*    Vitamins
      Vitamins are vital nutrients that help in the normal growth and development of the body and its component systems. They are very essential to normal body metabolism.

There are 13 forms of vitamin, which are grouped under the following:

·        Fat-soluble vitamins: These are vitamins that are stored in the fatty tissues of the body and the liver. They can stay in the body as reserves for days or even months. They are absorbed through the intestinal tract with the help of fats (lipids). Examples of fat-soluble vitamins are Vitamins A, D, E and K.

·        Water-soluble vitamins: This group of vitamins does not get stored in the body for long- they soon get excreted in urine. Because of this, water-soluble vitamins need to be replaced more often than fat-soluble vitamins. Vitamins C and all B Complex vitamins are in this group.

Major Sources of Vitamin
1.     Vitamin A: This is a fat-soluble vitamin with the chemical names, retinol, retinal, carotenoids etc. Here we have foods like carrot, sweet potato, spinach, egg, milk, butter, broccoli,  cold liver oil etc

2.     Vitamin B: This is a water-soluble vitamin with the chemical name thiamine. Common food sources include pork, yeast, brown rice, cauliflower, oranges, liver, eggs, cereal grains etc.

3.     Vitamin B2: A water-soluble vitamin with the chemical name riboflavin. Common food sources include bananas, okra, milk, yogurt, meat, fish, eggs, green beans etc.

4.     Vitamin B3: A water-soluble vitamin with the chemical name nuacin or niacinamide. Common food sources include liver, kidney, salmon fish, avocados, dates, tomatoes, leafy vegetables, asparagus, mushrooms, carrots, nuts, whole grains, chicken, beef, broccoli etc.

5.     Vitamin B5: A water-soluble vitamin with the chemical name pantothenic acid. Common food sources include meat, whole grains, fish ovaries, avocados, royal jelly etc.

6.     Vitamin B6: A water-soluble vitamin with the chemical names, pyridoxine, pyridoxamine, pyridoxal. Common food sources include vegetables, nuts, bananas, meats, whole grains etc.

7.     Vitamin B7: A water-soluble vitamin with the chemical name biotin. Common food sources include egg yolk, liver, some vegetables etc.

8.     Vitamin B9: A water-soluble vitamin with the chemical names folic acid, folinic acid. Common food sources include leafy vegetables, legumes, sunflower seeds, liver, bakers’ yeast etc.

9.     Vitamin B12: A water-soluble vitamin with the chemical names cyanocobalamin, hydroxocobalamin, methylcobalamin. Common food sources include eggs, fish, poultry, dairy products, soy products, milk etc.

10.    Vitamin C: A water-soluble vitamin with the chemical name ascorbic acid. Common food sources include fruits and vegetables.

11.    Vitamin D: A fat-soluble vitamin with the chemical names, ergocalciferol, cholecalciferol. Common food sources include early morning sun light, fatty fish, beef liver, mushrooms etc.

12.    Vitamin E: A fat-soluble vitamin with the chemical names tocopherols, tocotrienols. Common food sources include almonds, avocados, eggs, milk, nuts, unheated vegetable oils, leafy vegetables, whole grains, kiwi fruit etc.

13.    Vitamin K: A fat-soluble vitamin with the chemical names phylloquinone, menaquinones. Common food sources include leafy green vegetables, kiwi fruit, avocados etc.

Major Functions of Vitamin
i.                    Vitamin A promotes skeletal growth, normal teeth structure, healthy mucous membranes, healthy skin, eyes and hair; also essential for night vision;

iii.                Vitamin E prevents loss of other vitamins, aids blood flow to the heart, lowers blood cholesterol, strengthens capillary walls etc;
iv.               Vitamin B1 helps convert sugar and starch into energy, promotes digestion, prevents fatigue, promotes strong heart muscles etc;
v.                 Vitamin C is essential for the formation of collagen, aids in metabolism of amino acids and calcium, stops internal bleeding, strengthens blood vessels, reduces allergies, heals wounds and burns etc;
vi.               Vitamin K reduces risk of menstrual pains and internal bleeding.


                    Minerals
 Minerals are essential nutrients that are needed in small amounts to keep our body healthy. There are lots of minerals that are contained in the various foods we eat, which form the major sources of minerals in our body.

Major Sources of Mineral

iii.                Magnesium keeps nerves and muscles strong; it also helps in teeth and bone formation in infants etc.
iv.               Potassium keeps fluids balanced in blood and tissue; it helps in controlling blood pressure; it also allows nerves and muscles to work together etc.
v.                 Zinc is needed for growth and development of essential organs including reproductive organs; it helps to maintain a healthy immune system; it is very important for wound healing; it also helps the body use other nutrients.

             Water
    Water is the vital nutrient for good health. Our body weight is more of water (between 60%-70%).

Major Sources of Water
1.     Natural drinking water: This is the natural water we drink usually to quench our thirst.
