Small paper and grass skirts something seen on star (7)
I believe the answer is:
sunspot
'something seen on star' is the definition.
I can't tell whether this defines the answer.
'small paper and grass skirts' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'paper' becomes 'sun ' (The Sun, UK newspaper).
'and' is a charade indicator (letters next to each other).
'grass' becomes 'pot' (cannabis).
'skirts' means one lot of letters goes inside another (skirt can mean to go around).
'sun'+'pot'='sunpot'
's' inserted inside 'sunpot' is 'SUNSPOT'.
Can you help me to learn more?
(Other definitions for sunspot that I've seen before include "cause of magnetic storm" , "Dark cool patch on the surface of our nearest star" , "Cool solar area" , "Cool darker patch on our star" , "warm place" .)
