Sculptors possibly recalled pose in pieces lacking head (7)
I believe the answer is:
artists
'sculptors possibly' is the definition.
(sculptor is a kind of artist)
'recalled pose in pieces lacking head' is the wordplay.
'recalled' says the letters should be written backwards (to recall can mean to bring something back).
'pose' becomes 'sit' (synonyms).
'in' is an insertion indicator.
'pieces' becomes 'parts' ('part' can be a synonym of 'piece').
'lacking head' means to remove the first letter.
'sit' in reverse letter order is 'tis'.
'parts' with its initial letter removed is 'arts'.
'tis' put inside 'arts' is 'ARTISTS'.
(Other definitions for artists that I've seen before include "music performers?" , "They imagine" , "creative types may find themselves" , "Monet and Manet, for example" , "Painters" .)
