Stammered, leaving female to get changed (7)
I believe the answer is:
altered
'changed' is the definition.
(similar in meaning)
'stammered leaving female' is the wordplay.
'stammered' becomes 'faltered' ('falter' can be a synonym of 'stammer').
'leaving' is a deletion indicator.
'female' becomes 'f' (abbreviation).
'faltered' with 'f' removed is 'ALTERED'.
'to get' acts as a link.
(Other definitions for altered that I've seen before include "Converted" , "Change" , "Reformed" , "Different" , "Metamorphosed" .)
