Contrastive verb focus involves a verb copy in focus, optionally introduced by ta. The verb copy fails to display normal verbal behaviour in that it does not accept TAM markers. But some adverbial modifiers marking emphasis are acceptable; thus mes appears in Example 216. Kouwenberg & Muysken (1995: 212) also point to the acceptability of djis 'just' in predicate cleft.
