Split pea from spaghetti smeared gym wear (6)
I believe the answer is:
tights
'smeared gym wear' is the definition.
'tights' can be an answer for 'wear' (tights is a kind of wear). I am not certain of the 'smeared gym' bit.
'split pea from spaghetti' is the wordplay.
'split' is an anagram indicator.
'from' indicates named letters should be taken away.
'spaghetti' with 'pea' removed is 'sghtti'.
'sghtti' anagrammed gives 'TIGHTS'.
Can you help me to learn more?
(Other definitions for tights that I've seen before include "Pantihose" , "Leg garment" , "Nether garments for women or acrobats (6)" , "Close-fitting female garment" , "Women's garments" .)
