Near at hand or humid (5)
I believe the answer is:
close
I believe this clue is a double definition.
'near at hand' is the first definition.
(thesaurus)
'humid' is the second definition.
(I've seen this before)
(Other definitions for close that I've seen before include "Not far off" , "cul-de-sac" , "Meeting with a UFO?" , "Near - conclusion" , "On intimate terms" .)
