Nie jest łatwo być zawsze uczciwym.

QUESTION - I’ve seen quite a few sentences on CM whereby the adjective is declinated according to noun case, even though the adjective is not accompanied by a noun and the adjective does not follow a preposition. I’d always thought that a ‘stand alone’ adjective in a sentence (no noun pairing and no preposition beforehand) does not become declinated, except by gender. Are there exceptions to this? Thanks!
