I find I am almost nuts, crazy for ever (2,9)
I believe the answer is:
ad infinitum
'ever' is the definition.
(Latin phrase meaning forever)
'i find i am almost nuts crazy' is the wordplay.
'almost' means to remove the last letter (almost the whole word is kept).
'crazy' indicates an anagram.
'nuts' with its final letter removed is 'nut'.
'i'+'find'+'i'+'am'+'nut'='ifindiamnut'
'ifindiamnut' anagrammed gives 'AD INFINITUM'.
'for' acts as a link.
(Other definitions for ad infinitum that I've seen before include "Endlessly, forever (Lat.)" , "Indefinitely" .)
