Look good with spear (6)
I believe the answer is:
glance
'look' is the definition.
(I know that glance is a type of look)
'good with spear' is the wordplay.
'good' becomes 'g' (abbreviation).
'with' says to put letters next to each other.
'spear' becomes 'lance' (synonyms).
'g'+'lance'='GLANCE'
(Other definitions for glance that I've seen before include "Swift look" , "Batting stroke" , "Batsman's stroke" , "Stroke - gander" , "deflection" .)
