Scottish peasant in bed with sailor (6)
I believe the answer is:
cottar
'scottish peasant' is the definition.
'cottar' can be an answer for 'peasant' (cottar is a kind of peasant). I'm not sure about the 'scottish' bit.
'bed with sailor' is the wordplay.
'bed' becomes 'cot' (cot is a type of bed).
'with' means one lot of letters go next to another.
'sailor' becomes 'tar' (slang term for a sailor).
'cot'+'tar'='COTTAR'
'in' acts as a link.
Can you help me to learn more?
(Another definition for cottar that I've seen is " Highland peasant".)
