Bargain root vegetable, no longer equal (4)
I believe the answer is:
snip
'bargain root' is the definition.
'snip' can be an answer for 'bargain' (slang term for a good deal). I'm unsure of the 'root' bit.
'vegetable no longer equal' is the wordplay.
'vegetable' becomes 'parsnip' (parsnip is a type of vegetable).
'no longer' indicates named letters should be taken away.
'equal' becomes 'par'.
'parsnip' with 'par' taken out is 'SNIP'.
Can you help me to learn more?
(Other definitions for snip that I've seen before include "Cut quickly with a scissors" , "Surprisingly cheap item" , "bargain buy" , "Cut - certainty" , "Bargain - crop" .)
