===Relative clauses===
Relative clauses in Crow are complex and subject to theoretical debates. There are two types of relative clauses in Crow: lexically headed and non-lexically headed. There are two basic relativizers /'''ak'''/ and /'''ala'''/, several composite forms based on ''ala'' plus ''baa'' 'indefinite pronoun' and instances with no relativizer.  /'''ak'''/ indicates the subject of the relative clause is relativized and marks the subject as animate, and generally agentive. It can occur in both lexically and non-lexically headed clauses.  /'''ala'''/ may indicate a locative, temporal or manner adverbial is the head of the relative clause. In non-lexically headed relative clauses, /'''ala'''/ can sometimes be interpreted as the head of the clause itself. It can also occur in both lexically and non-lexically headed clauses. The relativizers are bound, with many exception, but they are generally prefixed to the word that contains the verb of the relative clause.

Relative clauses are marked with final determiners. If the definite referent of the relative clause has already been accounted in the discourse or is otherwise obvious, the relative clause is marked with the definite /''-sh''/. Relative clauses can also be marked with the indefinite determiner marker /''-m''/; generally this is used to imply that the referent is being introduced into the discourse for the first time. However, the nominal head is almost always marked by the indefinite determiner /''-m''/.
