Type of deal done working away during exercise (5-2)
I believe the answer is:
trade-in
'type of deal' is the definition.
'trade in' can be an answer for 'deal' (thesaurus). I am not sure about the 'type of' bit.
'done working away during exercise' is the wordplay.
'working' becomes 'on' (on can mean working or activated).
'away' is a deletion indicator.
'during' is an insertion indicator.
'exercise' becomes 'train' (training is a kind of exercising).
'done' with 'on' removed is 'de'.
'de' inserted into 'train' is 'TRADE-IN'.
Can you help me to learn more?
(Other definitions for trade-in that I've seen before include "Article used in part payment for another" , "Trained (anag.)" , "Article used in part-exchange" , "I daren't (anag)" , "Old item given in part payment for a new one" .)
