Language Foundations

Adjective agreement means that an adjective fits the noun it describes. In English, adjectives usually stay the same, whether the noun is singular or plural: a red car, two red cars. Some adjectives change only when you compare, like happy, happier, happiest.

An adjective describes a noun. It adds information about a person, place, animal, or thing, such as size, color, age, number, or quality. In English, adjectives usually come before the noun, or after the verb be, as in “The car is fast.”

In English, adverbs are words that give more detail about a verb, an adjective, or another adverb. They can tell how, when, where, or to what degree something happens. For example: slowly, today, here, very. They help make a sentence clearer and more exact.

In English grammar, agreement of the past participle means the participle can change so it matches the noun or pronoun it describes. This may happen in some passive structures or with certain verbs. Always check which word the participle refers to before choosing the form.

In English, an article is a small word placed before a noun, like a, an, or the. It shows whether we mean something in general, something not clearly identified, or something already known. Use a before a consonant sound. Use an before a vowel sound.

Gender is a grammar idea used for nouns and the words connected to them. In English, it often follows real sex or no sex: male, female, or neutral. Most nouns stay the same, but pronouns can change, for example he, she, and it.

In English, an interjection is a short word or sound that shows feeling or reaction. For example: “oh!”, “wow!”, “ouch!”. It often stands alone or comes at the start of a sentence. It makes speaking and writing sound more natural, lively, and expressive.

Interrogative pronouns are words you use to ask about a person, a thing, a choice, or possession. Common examples are who, what, which, and whose. They take the place of a noun in a question, so your question is clear and natural.

In English, negation shows that something is not true, does not exist, or does not happen. It often uses words like not, no, never, and nothing. With verbs, not usually comes after be, do, or modal verbs, for example: is not, do not, cannot.

A noun is a word used to name a person, a place, a thing, or an idea. It may refer to one item or to several. Some nouns are general, and some are special names. They often come after words like “a,” “an,” or “the” and help say what you mean.

In English, number shows if we talk about one person or thing, or more than one. This can change nouns, pronouns, and verbs. For example: cat and cats, he runs and they run. It helps you understand how many people, animals, or things are meant.

In English, personal pronouns are words used instead of a name or noun, such as I, you, he, she, it, we, and they. They show who is speaking or who we talk about. They make sentences shorter, clearer, and more natural to read and say.

In English, questions are used to ask for information, check if something is true, or ask for help. They often begin with words like who, what, where, when, why, and how. They can also change word order with do, be, or can. The voice and question mark also show a question.

In English, sentence structure is the order of words that makes a sentence clear and correct. A common pattern is subject, verb, object, like “She reads books.” Good structure helps people understand statements, questions, negatives, and longer sentences.

In English, subject-verb agreement means the verb changes to match the subject. A singular subject usually takes a singular verb. A plural subject usually takes a plural verb. For example: She works. They work. This helps make sentences correct and clear.

In English, a simple sentence gives one main idea. It usually has a subject and a verb. It can also include an object or other details. We use it to state a fact, ask a question, or give a clear instruction in a direct and easy way.

Types of Sentences shows the main sentence forms in English: statements, questions, commands, and exclamations. Each one has a different job. Learning them helps you understand meaning, notice tone, and write or speak in a clear and correct way.
