Creature one will see later? (9)
I believe the answer is:
alligator
'creature' is the definition.
(alligator is a kind of creature)
'one will see later?' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'will' could be 'll' (contracted form, as in 'he'll' - 'he will') and 'll' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for alligator that I've seen before include "beast to be seen in due course?" , "Cold-blooded killer, maybe" , "Long-jawed reptile" , "Large aquatic reptile" , "Amphibious reptile" .)
