Don't pick up so much stuff in Bow, being thus? (7)
I believe the answer is:
earless
'don't pick up' is the definition.
I can't tell whether this definition defines the answer.
'much stuff in bow being thus?' is the wordplay.
'much' means to remove the last letter (much but not all of the word).
'stuff in bow' becomes ''eart' ('heart' - heart is a kind of stuff - said with the 'H' dropped - a cockney accent.).
'being thus?' becomes 'less' (I am not sure about this - if you are sure you should believe this answer much more).
'eart' with its last letter removed is 'ear'.
'ear'+'less'='EARLESS'
'so' acts as a link.
Can you help me to learn more?
(Other definitions for earless that I've seen before include "like Vincent, late in life?" , "not listening then?" , "Lugs missing" , "apparently deaf?" , "Seals appear so" .)
