Give chaps a little time to admit one funny feeling (12)
I believe the answer is:
presentiment
'funny feeling' is the definition.
(thesaurus)
'give chaps a little time to admit one' is the subsidiary indication.
'give' becomes 'present' (presenting is a kind of giving**).
'chaps' becomes 'men' (I've seen this before).
'a little time' becomes 't'.
'to admit' means one lot of letters goes inside another.
'one' becomes 'i' (roman numeral).
'present'+'men'+'t'='presentment'
'presentment' placed around 'i' is 'presentiment'.
(Other definitions for presentiment that I've seen before include "An intuitive feeling" , "bad feeling" , "Intuitive foreboding" , "Feeling of apprehension" .)
