) clause to the noun that it modifies. In English, the relative pronouns are: who, whom, whose, whosever, whosesoever, which, and, in some treatments, that. In addition, English has various fused relative pronouns, which combine in one word the antecedent and the relative pronoun: what, whatever, whatsoever, whoever, whosoever, whomever, whomsoever, whichever, and whichsoever,

A relative pronoun links two clauses into a single complex clause. It is similar in function to a subordinating conjunction
Grammatical conjunction
In grammar, a conjunction is a part of speech that connects two words, sentences, phrases or clauses together. A discourse connective is a conjunction joining sentences. This definition may overlap with that of other parts of speech, so what constitutes a "conjunction" must be defined for each...

. Unlike a conjunction, however, a relative pronoun stands in place of a noun. Compare:
This is a house. Jack built this house. This is the house that Jack built.

Sentence (2) consists of two clauses, a main clause (This is the house) and a relative clause (that Jack built). The word that is a relative pronoun in some analyses. Within the relative clause, the relative pronoun stands for the noun phrase it references in the main clause (its antecedent
Antecedent (grammar)
In grammar, an antecedent is a noun, noun phrase, or clause to which an anaphor refers in a coreference. For example, in the passage "I did not see John because he wasn't there", "John" is the antecedent of the anaphor "he"; together "John" and "he" are called a coreference because they both refer...

s of the verb in the relative clause. In the example, the argument is the house, the direct object of built.

Other arguments can be relativised using relative pronouns:
Subject: Hunter is the boy who kissed Jessica.
Indirect object: Hunter is the boy to whom Jessica gave a gift.
Adpositional complement: Jack built the house in which I now live. (similarly with prepositions and prepositional phrases in general, for example These are the walls in between which Jack ran.)
Possessor: Jack is the boy whose friend built my house.

, do not have relative pronouns.

In English and German, different pronouns are sometimes used if the antecedent is a human being, as opposed to a non-human or an inanimate object (as in who/that). This is a bank. This bank accepted my identification. She is a bank teller. She helped us open an account.

With the relative pronouns, sentences (5) and (6) would read like this:
This is the bank that accepted my identification. She is the bank teller who helped us open an account.

In sentences (7) and (8), the words that and who are the relative pronouns. The word that is used because the bank is a thing; the word who is used because "she" is a person.

In some languages with relative clauses, such as Mandarin Chinese, there are no relative pronouns

A zero, in linguistics, is a constituent needed in an analysis but not realized in speech. This implies that there is a lack of an element where a theory would expect one. It is usually written with the symbol "", in Unicode .There are several kind of zeros....

. In English, the relative pronoun may be optionally omitted, particularly in speech, from a restrictive relative clause — that is, one which contributes to establishing the identity of the antecedent — if the relative pronoun would serve as the object of the verb or of a stranded preposition in the relative clause (as in This is the car I bought = This is the car that I bought or This is the car you heard of = This is the car of which you heard).
