However, little time for consideration (7)
I believe the answer is:
thought
'for consideration' is the definition.
(I've seen this before)
'however little time' is the wordplay.
'however' becomes 'though' (synonyms).
'little time' becomes 't' (abbreviation for time).
'though'+'t'='THOUGHT'
(Other definitions for thought that I've seen before include "Musing" , "That's an idea" , "Deliberated" , "Considered, believed" , "Fancy" .)
