Snags and ties getting support (9)
I believe the answer is:
drawbacks
'snags' is the definition.
(I've seen this before)
'ties getting support' is the wordplay.
'ties' becomes 'draws' ('draw' can be a synonym of 'tie').
'getting' means one lot of letters goes inside another.
'support' becomes 'back' (to back is to support or endorse).
'draws' placed around 'back' is 'DRAWBACKS'.
'and' acts as a link.
(Other definitions for drawbacks that I've seen before include "difficulties" , "Disadvantages, hindrances" , "Snags" .)
