Painful struggle reported at the geological feature (5)
I believe the answer is:
throw
'the geological feature' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'painful struggle reported' is the wordplay.
'painful struggle' becomes 'throe' (I've seen this in another clue).
'reported' indicates a 'sounds like' (homophone) clue.
'throe' is a homophone of 'THROW'.
'at' acts as a link.
Can you help me to learn more?
(Other definitions for throw that I've seen before include "Try not to win" , "Deliberately lose" , "Light rug" , "Organise party" , "Confuse - cast" .)
