Free from bride (3)
I believe the answer is:
rid
'free' is the definition.
(to be free of something is to be rid of it)
'from bride' is the wordplay.
'from' indicates the answer is hidden within the clue.
'RID' is hidden in the letters of 'bride'.
(Other definitions for rid that I've seen before include "Clear, remove" , "Free, relieve" , "Free from something unpleasant" , "Free, disencumber" , "Throw off, unburden" .)
