Part of the hospital set up by local Yank (4)
I believe the answer is:
draw
'local yank' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'part of the hospital set up' is the wordplay.
'part of the hospital' becomes 'ward' ('ward' is part of 'hospital').
'set up' says the letters should be written in reverse.
'ward' reversed gives 'DRAW'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for draw that I've seen before include "very attractive event" , "Tied score; sketch" , "Snag" , "Take in (a breath), attraction" , "Collect one's pay" .)
