Good dressing but a little light? (5)
I believe the answer is:
glint
'a little light?' is the definition.
'glint' can be an answer for 'light?' (I've seen this before). I am unsure of the 'a little' bit.
'good dressing' is the wordplay.
'good' becomes 'g' (abbreviation).
'dressing' becomes 'lint' (I've seen this in other clues).
'g'+'lint'='GLINT'
'but' is the link.
Can you help me to learn more?
(Other definitions for glint that I've seen before include "Flash of reflected light" , "Give out small flashes of light" , "Brief indication" , "Shine" , "Momentary flash of light" .)
