Sailor with party workers in the middle? (7)
I believe the answer is:
abdomen
'the middle?' is the definition.
(I've seen this in another clue)
'sailor with party workers' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'with' says to put letters next to each other.
'party' becomes 'do' (do is a kind of party).
'workers' becomes 'men' (men can mean staff or employees).
'ab'+'do'+'men'='ABDOMEN'
'in' is the link.
(Other definitions for abdomen that I've seen before include "Part of body containing the stomach" , "Insect's body part" , "Belly" , "A main part of the body" , "Part of the body below chest and diaphragm" .)
