In adversative coordination, the manual marker but occurs between the first and the second clause, as confirmed by the presence of the following prosodic non-manual markings signalling the clause boundary between the first and the second conjunct: a pause in the signing stream, eye blink and chin down (cd) after the last sign of the first clause. These non-manuals marking the end of the first clause precede the manual marker but.
