Quartet her editors partly bound (8)
I believe the answer is:
tethered
'bound' is the definition.
(similar in meaning)
'quartet her editors partly' is the wordplay.
'partly' indicates a hidden word (part of the clue is used).
'TETHERED' can be found hidden inside 'quartet her editors'.
(Other definitions for tethered that I've seen before include "Bound" , "Not free" , "Confined in range by tied rope" , "on a leash" , "Of animal, with rope fastened to prevent straying" .)
