Sometimes lazy female star without appeal (5)
I believe the answer is:
susan
'sometimes lazy female' is the definition.
I can't tell whether this definition defines the answer.
'star without appeal' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'appeal' becomes 'SA' (old-fashioned abbreviation for sex appeal).
'sun' placed around 'sa' is 'SUSAN'.
Can you help me to learn more?
(Other definitions for susan that I've seen before include "with blooming black eye?" , "Server at table's no lazy" , "Black-eyed -; lazy -" , "- - Sarandon (films)" , "woman" .)
