One burns reportedly tough goat (4)
I believe the answer is:
ibex
'tough goat' is the definition.
(wild goat)
'one burns reportedly' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'reportedly' could be 'e' (I've seen this in other clues) and 'e' 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 ibex that I've seen before include "Large-horned wild goat" , "Wild mountain goat" , "Large-horned mountain goat" , "Wild goat with large recurved horns" , "Mountain goat with curving horns" .)
