Lay with some hairy thing (3)
I believe the answer is:
air
'lay' is the definition.
(I've seen this before)
'some hairy thing' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'AIR' can be found hidden inside 'hairy thing'.
'with' is the link.
(Other definitions for air that I've seen before include "Broadcast; tune" , "Mixture of gases, especially oxygen" , "Tune (on the G string?)" , "A melody or attitude" , "An impressive manner or tune" .)
