This pot some occasionally steal? (6)
I believe the answer is:
tiptoe
'steal?' is the definition.
(thesaurus)
'this pot some occasionally' is the wordplay.
'occasionally' means one should take alternating letters (letters taken at regular intervals or occasions).
'this'+'pot'+'some'='thispotsome'
The alternate letters of 'thispotsome' are 'TIPTOE'.
(Other definitions for tiptoe that I've seen before include "or get a bit higher on this?" , "Creep" , "Move delicately" , "Walk very lightly - musically through the tulips" , "Go gently" .)
