Bear on rampage near pit (7)
I believe the answer is:
pertain
'bear on' is the definition.
(synonyms)
'rampage near pit' is the wordplay.
'rampage' is an anagram indicator (I've seen 'rampaging' mean this (I've seen this in other clues)).
'near'+'pit'='nearpit'
'nearpit' anagrammed gives 'PERTAIN'.
(Other definitions for pertain that I've seen before include "Have relevance" , "Painter (anag) - relate (to)" , "Be related or applicable (to something)" , "Painter inclined to be relevant" , "Refer" .)
