Shoe for sale, shilling off, tatty (6)
I believe the answer is:
loafer
'shoe' is the definition.
(Loafer is an example)
'for sale shilling off tatty' is the wordplay.
'shilling' becomes 's' (abbreviation e.g. Lsd - pounds, shillings, pence).
'off' indicates named letters should be taken away (some letters taken off).
'tatty' indicates anagramming the letters.
'for'+'sale'='forsale'
'forsale' with 's' taken out is 'forale'.
'forale' anagrammed gives 'LOAFER'.
(Other definitions for loafer that I've seen before include "Lazy fellow or soft shoe" , "Layabout" , "Lazy type" , "one going on foot?" , "Fanciful baker" .)
