Left in car, finally digest a little verse (7)
I believe the answer is:
couplet
'a little verse' is the definition.
'couplet' can be an answer for 'verse' (I've seen this before). I'm not sure about the 'a little' bit.
'left in car finally digest' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'car' becomes 'coupe' (coupe is a kind of car).
'finally' indicates one should take the final letters.
The last letter of 'digest' is 't'.
'l' going within 'coupe' is 'couple'.
'couple'+'t'='COUPLET'
Can you help me to learn more?
(Other definitions for couplet that I've seen before include "Pair of lines in poetry" , "Pair of verse lines" , "piece of poetry" , "Two lines of verse, often rhyming" , "bit of poetry" .)
