Gander caught in golf course (6)
I believe the answer is:
glance
'gander' is the definition.
(I've seen this before)
'caught in golf course' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' is an insertion indicator.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'course' becomes 'lane' (a lane is a path or course).
'g'+'lane'='glane'
'c' going within 'glane' is 'GLANCE'.
(Other definitions for glance that I've seen before include "oblique movement" , "Flash" , "Take a brief or hurried look" , "fly off" , "Butcher's" .)
