Like Cinerama, possibly? (8)
I believe the answer is:
american
'like' is the definition.
Although both the answer and definition are adjectives, I cannot understand how they can define each other.
'cinerama possibly?' is the wordplay.
'possibly?' is an anagram indicator (I've seen 'possibly' mean this).
'cinerama' anagrammed gives 'AMERICAN'.
Can you help me to learn more?
(Other definitions for american that I've seen before include "one like Garfield?" , "Beauty of Film" , "Nationality of Edgar Allan Poe" , "From across the pond" , "countryman" .)
