4.3.1. The Verb-adjacency requirement
Both adjunct and argument wh-phrases in Romanian show obligatory adjacency with the verbal complex (i.e., verbal head and clitic cluster). Consider the examples in (8);
(8) a. Pe cine (* la tine) ai chemat (la tine)?
PE who (at you) AUX.2SG called (at you)
‘Whom did you invite to your place?’
b. (Mîine) Cine (*mîine) nu mai pleacă (mîine)?
(tomorrow) who (*tomorrow) not more leave.3SG.PR (tomorrow)
‘Who isn’t leaving tomorrow anymore?’
c. Cui (*deja) ai telefonat (deja)?
whom.DAT. (*already) AUX.2SG phoned (already)?
‘Whom did you already call?’
d. (La Toronto) Cînd (*la Toronto) plecăm (la Toronto)?
(at Toronto) when (*at Toronto) leave.1PL.PR (at Toronto)
‘When do we leave for Toronto?’
e. (Ion) Cu ce (* Ion) te-a supărat (Ion)?
(Ion) with what (* Ion)CL.2SG.ACC-AUX.3SG upset (Ion)
‘What did Ion upset you with?’
f. (Pe Mihai) Cum (* pe Mihai) l-ai
(PE Mihai) how (*PE Mihai) CL.3SG.ACC.M-AUX.2SG
hotărît (pe Mihai) să vină?
convinced (PE Mihai) SUBJ. come
‘How did you convince Mihai to come?’
The examples in (8) show that wh-movement proceeds to a position that is adjacent to the verbal complex, with no constituent allowed to intervene between the wh-phrase and the verbal complex.
