Turkey reluctant -- and cross (8)
I believe the answer is:
traverse
'cross' is the definition.
(I know that cross can be written as traverse)
'turkey reluctant' is the wordplay.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'reluctant' becomes 'averse' (averse can mean reluctant or opposing).
'tr'+'averse'='TRAVERSE'
'and' is the link.
(Other definitions for traverse that I've seen before include "Travel across or pass over" , "Cross sideways" , "get across" , "Ski diagonally across (a slope)" , "In mountaineering, a steep slope to be crossed from side to side" .)
