Small church area given up for Welshman? (5)
I believe the answer is:
evans
'welshman?' is the definition.
(common Welsh surname)
'small church area given up' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'church area' becomes 'nave' (I've seen this in another clue).
'given up' says the letters should be written backwards (in a down clue, letters go up).
's'+'nave'='snave'
'snave' back-to-front is 'EVANS'.
'for' is the link.
(Other definitions for evans that I've seen before include "Female writer's real name" , "Dame Edith -, English actress" , "Lee --, British comedian" , "Welshman" , "dame of acting fame" .)
