Mother with 50p, say, brought back root vegetable (6)
I believe the answer is:
manioc
'root vegetable' is the definition.
'manioc' can be an answer for 'root' (I've seen this before). I'm not certain of the 'vegetable' bit.
'mother with 50p say brought back' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'with' means one lot of letters go next to another.
'50p say' becomes 'coin' (fifty pence is a type of coin).
'brought back' says the letters should be written in reverse.
'coin' reversed gives 'nioc'.
'ma'+'nioc'='MANIOC'
Can you help me to learn more?
(Other definitions for manioc that I've seen before include "root" , "source of starch" , "Cassava" , "tropical plant" .)
