Result strangely in a glossy appearance (6)
I believe the answer is:
lustre
'glossy appearance' is the definition.
'lustre' can be an answer for 'appearance' (lustre is a kind of appearance). I am not sure about the 'glossy' bit.
'result strangely' is the wordplay.
'strangely' indicates an anagram.
'result' anagrammed gives 'LUSTRE'.
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for lustre that I've seen before include "Gentle sheen, soft glow" , "Gloss, brightness" , "Radiance; reflective surface" , "Result (anag) -- gloss" , "Polish" .)
