It's not very important, but they said to taste it before they throw it away (8)
I believe the answer is:
trifling
'away' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'it's not very important but they said to taste it before they throw it' is the wordplay.
I cannot quite understand how this works, but
'said' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'throw' could be 'fling' (fling is a kind of throw) and 'fling' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for trifling that I've seen before include "Paltry" , "Dallying; petty" , "Inconsequential" , "Minor" , "Fooling around; unimportant" .)
