Afrikaans: finite interrogative complement clauses : construction forms

Finite interrogative complement clauses may be introduced by the complementiserof if/whether or a WH-word (wanneer when, wat what, waar where, hoekom why, watter what/which). Interrogative complement clauses introduced by of íf/whether are general interrogatives (indirect yes/no-questions), as exemplified by (1), whereas interrogative complement clauses introduced by WH-words are specific interrogatives (indirect WH-questions), as exemplified by (2). Like finite declarative complement clauses (see the section on syntactic positions of finite declarative complement clauses), interrogative complement clauses are most frequently used as object clauses, but are also used as subject clauses and predicate clauses (discussed in more detail here).
