Welcome the writer coming back to stay (7)
I believe the answer is:
embrace
'welcome' is the definition.
(I've seen this before)
'the writer coming back to stay' is the wordplay.
'the writer' becomes 'me' (the person who is writing these clues).
'coming back' says the letters should be written in reverse.
'to stay' becomes 'brace' (I can't justify this - if you can you should give a lot more credence to this answer).
'me' written backwards gives 'em'.
'em'+'brace'='EMBRACE'
Can you help me to learn more?
(Other definitions for embrace that I've seen before include "affectionate greeting" , "Include (in one's arms)" , "Include - clasp" , "Cuddle" , "bear-hug?" .)
