Degrees of comparison Degrees of comparison refer to adjectives being written in different forms to compare one, two or more nouns which are words describing persons, places and things. The three different forms of comparison are • Positive degree. • Comparative degree. • Superlative degree. Positive degree When we speak about only one person or thing, we use the Positive degree. Examples: This house is big. Comparative degree When we compare two persons or two things with each other, Examples: This house is bigger than that one. (Comparative degree) Superlative degree When we compare more than two persons or things with one another, Examples: This is the biggest house in this street. (Superlative) Tense A tense is a form taken by a verb to show the time of an action. There are three main tenses: Present tense: Things that are true when the words are spoken or written; or are generally true; or for some languages will be true in the future Past tense: Things that were true before the words were spoken or written Future tense: Things that will or might be true after the words are spoken or writtenHomophones Two or more words (such as knew and new or meat and meet) that are pronounced the same but differ in meaning, origin, and often spelling. Synonym A word or phrase that means exactly or nearly the same as another word or phrase in the same language, for example shut is a synonym of close.Antonym A word opposite in meaning to another (e.g. bad and good).Phrasal verb A phrasal verb consists of a verb and a preposition or adverb that modifies or changes the meaning; give up is a phrasal verb that means stop doing something, which is very different from give.
