Indefinitely

I think it could be either:

forever

sinedie

'indefinitely' is the definition.
(synonyms)

This is all the clue.

(Other definitions for forever that I've seen before include "continually" , "as diamonds are" , "Till hell freezes over" , "Eternally" , "till Doomsday" .)

I've seen this clue in the Evening Standard.
