PredAdjNumAgr: Predicative adjectives show only number agreement.
(1) a virág szép.
the flower beautiful
’The flower is beautiful.’
(2) a virág-ok szép-ek.
the flower-pl beautiful-pl
’The flowers are beautiful.’
(3) a virág-ok szép-ek vol-t-ak.
the flower-pl beautiful-pl cop-pst-3pl

Adjectives can only take suffixes when they are in the predicative position. Predicative adjectives agree with the subject (1)-(3), but unlike verbs, they only reflect the number of the subject (cf. Lengyel 2000a: 142‒150).
