Crossword Genius

Bananas in crate for sure (7)

Ross

I believe the answer is:

certain

'sure' is the definition.
(I know that sure can be written as certain)

'bananas in crate' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'in'+'crate'='incrate'
'incrate' anagrammed gives 'CERTAIN'.

'for' is the link.

(Other definitions for certain that I've seen before include "Known beyond doubt" , "Unquestionable" , "bound" , "Convinced" , "Nice art (anag)" .)

I've seen this clue in The Sun.
