Consideration despite the fact that time's short (7)
I believe the answer is:
thought
'consideration' is the definition.
(thesaurus)
'despite the fact that time's short' is the wordplay.
'despite the fact that' becomes 'though' ('though' can be a synonym of 'despite the fact that').
'short' indicates taking the first letters.
The first letter of 'times' is 't'.
'though'+'t'='THOUGHT'
(Other definitions for thought that I've seen before include "Thinking process" , "Fancy" , "Deliberation" , "Deliberated" , "Supposed" .)
