In (8), and (11), the fronted constituent is the subject. On the other hand, in (9), the fronted constituent is the object. Another example of a fronted constituent in Tagalog is, "wh-phrases." Wh-phrases include interrogative questions that begin with: who, what, where, when, why, and how. In Tagalog, wh-phrases occur to the left of the clause. For example, in the sentence, 'Who are you?'", "which translates to, '"Sino ka?"' occurs to the left of the clause. The syntactic tree of this sentence is found in (12a). As we can see in (12a), the complementizer position is null. However, in the case where an overt complementizer is present, Sabbagh (2014) proposes that the wh-phrase lowers from Spec, CP, and adjoins to TP when C is overt (12b). The operation in (12b) is known as, WhP lowering.
