Good person, with look back, streaks (5)
I believe the answer is:
stria
'good person with look back streaks' is the definition.
I can't tell whether this defines the answer.
'good person with look back' is the wordplay.
'good person' becomes 'st' (saint).
'with' is a charade indicator (letters next to each other).
'look' becomes 'air' (something might have a certain air or look).
'back' says the letters should be written in reverse.
'air' written backwards gives 'ria'.
'st'+'ria'='STRIA'
Can you help me to learn more?
(Other definitions for stria that I've seen before include "band" , "Lines" , "streak" .)
