Cracked her clue, keeping female happy (8)
I believe the answer is:
cheerful
'happy' is the definition.
(associated in meaning)
'cracked her clue keeping female' is the wordplay.
'cracked' is an anagram indicator.
'keeping' indicates putting letters inside (some letters kept inside).
'female' becomes 'f' (common abbreviation).
'her'+'clue'='herclue'
'herclue' is an anagram of 'cheerul'.
'cheerul' enclosing 'f' is 'CHEERFUL'.
(Other definitions for cheerful that I've seen before include "Contented" , "In a happy mood" , "Genial" , "In good humour, quite jolly" , "Bright" .)
