inevitable

'sure to happen' is the definition.
I can't tell whether this defines the answer.

'false alibi event' is the wordplay.
'false' indicates anagramming the letters.
'alibi'+'event'='alibievent'
'alibievent' anagrammed gives 'INEVITABLE'.

Can you help me to learn more?

(Other definitions for inevitable that I've seen before include "Certain to happen" , "Unavoidable, fated" , "Inescapable" .)

I've seen this clue in The Times.
