Actor MacLachlan
I believe the answer is:
kyle
'actor maclachlan' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kyle that I've seen before include "Transport system with floating trains" , "Narrow channel (Scots), rhymes with dossier" , "- - of Lochalsh" , "Narrow sea channel (in Scotland)" .)
