Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'придаточное определительное' (relative/adjective clause).
- Russian often uses comma+что where English uses 'that' without a comma for noun clauses.
- The subjunctive mood is sometimes used in English noun clauses after certain verbs (e.g., 'suggest', 'insist'), which has no direct equivalent in Russian.
Common Mistakes
- Confusing it with a relative (adjective) clause.
- Using a comma before 'that' when it introduces a noun clause as object (e.g., 'I know, that...' is incorrect).
- Misidentifying the function (e.g., thinking 'where she went' in 'I know where she went' is an adverbial clause; here it's the object noun clause).

A noun phrase is centred on a single noun or pronoun (e.g., 'the quick brown fox'). A noun clause contains a subject and a verb and functions as a noun (e.g., 'What the fox did').
Yes, but only in noun clauses expressing yes/no questions, where 'if' is synonymous with 'whether'. Example: 'I don't know if she's coming.'
Find a clause (subject+verb) that you could replace with a simple pronoun like 'it' or 'something'. If you can, it's likely functioning as a noun clause.
