Scuff's centre needs extra line to bind each shoe strap? (6)
I believe the answer is:
uppers
'scuff's centre needs extra line to bind each shoe strap?' is the definition.
I can't tell whether this definition defines the answer.
'scuff's centre needs extra line to bind each' is the wordplay.
'centre' says to take the centre.
'needs extra line' becomes 'ps' (I can't explain this - if you can you should believe this answer much more).
'to bind' is an insertion indicator.
'each' becomes 'per' ('per' can mean for each).
The centre of 'scuff' is 'u'.
'ps' going around 'per' is 'ppers'.
'u'+'ppers'='UPPERS'
Can you help me to learn more?
(Other definitions for uppers that I've seen before include "pills" , "Out of luck, one may be on these" , "Parts of shoes above the sole" , "the poor are on?" , "The 25 [PENNILESS] are on these" .)
