The last to be involved in a desperate fight? (5)
I believe the answer is:
ditch
'a desperate fight?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'the last to be involved' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
The remaining letters 'dich' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ditch that I've seen before include "Type of trench" , "Moat" , "Narrow channel" , "Drainage trench" , "Jettison" .)
