Enormous cat in it (7)
I believe the answer is:
titanic
'enormous' is the definition.
(I've seen this in another clue)
'cat in it' is the wordplay.
'cat in it' can be anagrammed to 'TITANIC'.
Though, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for titanic that I've seen before include "Of great force or power, like the ill-fated ship" , "Ill-fated liner" , "Of exceptional strength or size" , "Huge, like doomed liner that struck iceberg" , "Having huge strength - ship that famously sunk" .)
