Mountain guide forgets her packed bags (6)
I believe the answer is:
sherpa
'mountain guide' is the definition.
(I've seen this in another clue)
'forgets her packed bags' is the wordplay.
'bags' indicates a hidden word.
'SHERPA' can be found hidden inside 'forgets her packed'.
(Other definitions for sherpa that I've seen before include "Asian language" , "Skilled Himalayan mountaineer" , "Such as Tensing_Norgay" , "Phrase for Himalayan mountain climber" , "Highly competent guide" .)
