Kind of bottle sailors found in end (5-3)
I believe the answer is:
screw-top
'kind of bottle' is the definition.
'screw top' can be an answer for 'bottle' (I've seen this before). I'm not certain of the 'kind of' bit.
'sailors found in end' is the wordplay.
'sailors' becomes 'crew' (as in a ship's crew).
'found in' is an insertion indicator.
'end' becomes 'stop' (synonyms).
'crew' put within 'stop' is 'SCREW-TOP'.
Can you help me to learn more?
(Another definition for screw-top that I've seen is " Type of bottle".)
