Bear became hot and wild (2,7)
I believe the answer is:
go through
'bear' is the definition.
(both can mean to experience)
'became hot and wild' is the wordplay.
'became' becomes 'got' ('get' can be a synonym of 'become').
'hot' becomes 'h' (abbreviation eg on taps).
'and' says to put letters next to each other.
'wild' becomes 'rough' (both can mean violent).
'got'+'h'+'rough'='GO THROUGH'
(Other definitions for go through that I've seen before include "be accepted" , "brave" , "Face" , "Use up - experience" , "Suffer from" .)
