Meaning and Definition
A clause that modifies a noun or noun phrase and is introduced by a relative pronoun (e.g., who, which, that) or a relative adverb (e.g., where, when).
A type of subordinate clause that provides additional information about an antecedent noun. It can be defining (restrictive), essential to the meaning of the sentence, or non-defining (non-restrictive), providing extra, non-essential information.
Dialectal Variation
British vs American Usage
Differences
Minimal. British English may slightly favour 'which' in non-defining clauses and be more tolerant of 'which' to refer to people in formal contexts (e.g., 'Our team, which includes several experts...'). American English strongly prefers 'that' for defining clauses referring to things and reserves 'which' for non-defining clauses.
Connotations
None.
Frequency
Equally common and essential in both varieties for formal writing and complex expression.

Common Mistakes When Using “relative clause”
- Omitting the relative pronoun when it is the object ('The man Ø I saw' is acceptable). Omitting it when it is the subject is incorrect (*'The man Ø lives next door is a doctor.').

- Misplacing the clause: *'I bought a car from my neighbour which was cheap.' (Was the neighbour cheap?).
FAQ
Frequently Asked Questions
In modern usage, particularly in American English, 'that' is used for defining clauses (essential info), and 'which' is used for non-defining clauses (extra info, set off by commas). British English is sometimes more flexible with 'which' in defining clauses.
You can omit the relative pronoun only when it is the object of the relative clause. E.g., 'The man (whom) I saw' is fine. You cannot omit it when it is the subject. E.g., 'The man who saw me' cannot become '*The man saw me' with the same meaning.
A contact clause is another term for a defining relative clause where the relative pronoun (that, who, which) has been omitted because it functions as the object. E.g., 'The book I read' (instead of 'The book that I read').
