jaditi

1. dated formal (someone) to grieve; to cause sorrow; to make miserable
   Nemoj da jadiš majku svojim ponašanjem. — Don't grieve your mother with your behaviour.
   Jadi je pomisao da će ostati sama. — The thought of being left alone torments her.
2. dated formal (jaditi se, to someone) to complain; to lament; to bemoan one's lot
   Jadila mi se da je niko ne razume. — She complained to me that nobody understands her.
   Stalno se jadi kako nema para. — He's always moaning that he has no money.

Today both transitive jaditi and reflexive jaditi se sound bookish and dated. The neutral modern form is jadati se (jadati se nekome na nešto): Jadala mi se da je niko ne razume; Stalno se jada kako nema para.
