Parts of Speech in English: Nouns, Verbs, Adjectives, and Adverbs - Part 1

In English, there are 8 main parts of speech: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections. In part 1, we will focus on two core categories: nouns and verbs. Understanding these clearly will help you build accurate and richer sentences.

1. Nouns

A noun is a word used to refer to a person, place, thing, idea, or concept. There are two main types of nouns: common nouns and proper nouns.

• Common nouns: dog, city, happiness
• Proper nouns: John, Paris, Facebook

Nouns can act as subjects, objects, or complements in a sentence. For example:

• Subject: The cat is sleeping.
• Object: I see a dog.
• Complement: She is a teacher.

Common suffixes used to form nouns include:

-tion, -sion, -ment, -ness, -er, -or, -ship, -ity, -ist, -ism;

Meaning of common noun-forming suffixes:

-tion / -sion often indicate an action or process.

Example: "information" refers to the process of conveying information, and "decision" refers to the process of deciding.

-er / -or often indicate the doer of an action.

Example: "teacher" is a person who teaches, and "actor" is a person who performs. However, there are exceptions such as "computer," which is not a person.

-ship often indicates a state, condition, or relationship.

Example: "friendship" means the state of being friends, and "leadership" means the quality or role of leading.

-ist often indicates a person associated with an ideology or profession.

Example: "artist" means an art practitioner, and "scientist" means a person who works in science.

-ism often indicates a system of beliefs, a theory, or a movement.

Example: "capitalism" is an economic system, and "realism" is a school of thought or style.

Position of nouns:

• At the beginning of a sentence as the subject: Dogs are loyal animals.
• Usually after an article (a, an, the) or an adjective. Example: a book, the red car.
• Can appear after a preposition. Example: in the house, on the table.
• Can appear after a verb. Example: I have a dog.

Note: Some nouns can be countable or uncountable. For example, "apple" is countable, while "water" is uncountable.

Countable Nouns vs. Uncountable Nouns

Countable nouns	Uncountable nouns
Can be separated and counted individually: person, tree, car, etc.	Cannot normally be separated and counted individually: liquids, materials, abstract concepts, or mass nouns such as water, air, information, equipment, furniture, etc.
Can have singular and plural forms (add s/es): one book, two books, etc.	Usually used in singular meaning: we do not normally say "one water" or "two informations."
Can be used with a/an/the/one: a cat, an apple, etc.	Not used with a/an directly: we do not say "a water" or "an information."
Can be used with numbers: three dogs, five cars, etc.	Not normally used with direct numbers: we do not say "three waters" or "five informations."
Many, a number of, the number of, few/a few	Much, a lot of, a great deal of, little/a little

Some uncountable nouns look plural in form: news, economics, physics, mathematics.

Note: Some nouns can be both countable and uncountable depending on context. For example, "chicken" is countable when referring to the animal (a chicken, two chickens), but uncountable when referring to meat (some chicken, a lot of chicken).

Some uncountable nouns can be used in a countable context when referring to type or measured serving. For example, "coffee" is uncountable when referring to the liquid, but can be countable when referring to a type of coffee (a coffee, two coffees) or a serving unit (a cup of coffee).

Possessive Case

The possessive case is used to express ownership or a relationship between nouns.

Important Usage Rules

• Singular noun: add 's

  • the boy's book (the book of the boy)
  • Mary's car (the car of Mary)

• Plural noun already ending with s: add only '

  • the students' classroom
  • my parents' house

• Irregular plural noun (not ending with s): add 's

  • children's toys
  • men's clothing

• Use of for objects, abstract concepts, or long noun phrases

  • the roof of the house
  • the name of the book

's is often used for people or animals, while of is often used for objects or abstract concepts. However, usage can be flexible and context-dependent.

2. Verbs

A verb is a word used to express an action, state, or existence. There are three main types of verbs: action verbs, linking verbs, and auxiliary verbs.

• Action verbs: run, eat, write
• Linking verbs: be, seem, become
• Auxiliary verbs: have, do, will

Verbs can be inflected by tense, person, and number. For example:

• Simple present: I eat breakfast every day.
• Simple past: She ran to the store yesterday.
• Simple future: They will go to the park tomorrow.

2.1 Common Verb-Forming Suffixes

-ize, -ise,...

Meaning of common verb-forming suffixes:

-ize / -ise often indicate causing something to become a certain way.

Example: "realize" means to become aware, and "organize" means to arrange systematically.
