About female, much is up in the air (5)
I believe the answer is:
aloft
'up in the air' is the definition.
(aloft means above or overhead)
'about female much' is the wordplay.
'about' is an insertion indicator.
'female' becomes 'f' (common abbreviation).
'much' becomes 'a lot' (synonyms).
'f' going within 'alot' is 'ALOFT'.
'is' is the link.
(Other definitions for aloft that I've seen before include "up the mast" , "Heading for heaven" , "Above - on top" , "In the rigging, up high" , "Up in the air, high above" .)
