Stitched pockets tailor's coat covered (6)
I believe the answer is:
strewn
'covered' is the definition.
(similar in meaning)
'stitched pockets tailor's coat' is the wordplay.
'stitched' becomes 'sewn' (synonyms).
'pockets' means one lot of letters goes inside another.
'coat' means to remove the middle letters (only the letters which coat the word are used).
'tailor' with its centre taken out is 'tr'.
'sewn' going around 'tr' is 'STREWN'.
(Other definitions for strewn that I've seen before include "Scattered about, littered" , "Cast about" , "Scatttered about untidily" , "Scattered loosely" , "Spread everywhere" .)
