adekvatan

1. adequate; appropriate
   Nismo dobili adekvatan odgovor na pitanje. — We didn't get an adequate answer to the question.
   Pacijent nije imao adekvatnu negu. — The patient didn't have proper care.

Mostly used of answers, measures and conditions; unlike Russian адекватный, it is less often used of a person to mean 'sensible' or 'reasonable'.
