Spring traps of that girl guide (6)
I believe the answer is:
sherpa
'girl guide' is the definition.
'sherpa' can be an answer for 'guide' (Himalayan mountain guide). I'm not sure about the 'girl' bit.
'spring traps of that' is the wordplay.
'spring' becomes 'spa' (spa can mean a mineral spring).
'traps' indicates putting letters inside.
'of that' becomes 'her' (I can't explain this - if you can you should believe this answer much more).
'spa' enclosing 'her' is 'SHERPA'.
Can you help me to learn more?
(Other definitions for sherpa that I've seen before include "Highly competent guide" , "Skilled Tibetan mountaineer" , "guide to range" , "Asian language" , "Such as Tensing_Norgay" .)
