Bind queen's lavender, stripping outer pieces (7)
I believe the answer is:
enslave
'bind' is the definition.
(I've seen this before)
'queen's lavender stripping outer pieces' is the wordplay.
'stripping outer pieces' indicates a hidden word (some letters must be stripped from the clue).
'ENSLAVE' can be found hidden inside 'queens lavender'.
(Other definitions for enslave that I've seen before include "Force into servitude" , "Reduce to serfdom" , "Reduce to subservience" , "Save Len (anag.)" , "Bind" .)
