Remove, separate (6)
I believe the answer is:
detach
I believe this is a double definition.
'remove' is the first definition.
(I've seen this before)
'separate' is the second definition.
(detaching is a kind of separating)
(Other definitions for detach that I've seen before include "Separate one part from another" , "Separate, disconnect" , "Take away -- the cad (anag)" , "His timid love song (T. S. Eliot)" , "Disengage (something) and remove it" .)
