All (who, whom, whose, where, when, which) except “that” can be used. It gives extra information about the name it describes (special name or already defined name) and this information is not required for understanding the sentence. Adjective Clause is not separated from the main sentence by commas. “Who, whom, that, which, whose, where, when, why” is used. When used in a sentence, it gives us descriptive and necessary information about the name it describes. Adjective clause sentences can be used in two different types: Defining Adjective Clause However, sometimes there may be differences. Note: We should be careful about the synchronization between the adjective clause and the main sentence.

Why: In general, ‘why’ or ‘that’ can be used after the word reason.

When the name described in the When: Adjective clause clause is a time word such as day, hour or year, ‘when’ is used as an pronoun. In order to understand whether a place name in English is used as an object / subject or as an indirect complement, it is necessary to ask these items where and what questions. If the place name to be considered is a subject or object rather than an indirect complement, ‘which’ or ‘that’ is used instead of ‘where’.

Where: Where the name defined in the Adjective clause statement declares a place, ‘where’ is used.

It can be used in place of every pronoun except “whose”.

That: This pronoun can also be called wildcard pronoun.Which pronoun may refer not only to a name preceding him, but also to the entire sentence. Which: We use which pronoun to characterize animals or inanimate objects in a sentence.

Whose: “his, her, their etc.” in the Adjective clause sentence If a possessive pronoun like “refers to the name he will describe in the main sentence,” whose “pronoun is used.

The only difference of Whom is that it is used in more formal sentences.

Who / Whom: If we are a person or a community of people that we will describe when forming a sentence, who or who is used.

(in the library) but here the name which is described will be “every laptop”, not “library”. In this sentence, a place piece has entered between the adjective clause and the name he describes.
