Split peas, absurd price (8)
I believe the answer is:
separate
'split' is the definition.
('separate' can be a synonym of 'split')
'peas absurd price' is the wordplay.
'absurd' indicates anagramming the letters.
'price' becomes 'rate' (I've seen this in other clues**).
'peas' anagrammed gives 'sepa'.
'sepa'+'rate'='SEPARATE'
(Other definitions for separate that I've seen before include "Divided or detached" , "Distinct, not joined" , "Divide, part" , "Not joined or touching" , "Not joined or united with others" .)
