This word consists of the prefix 'un-' and 'gerechtfertigt' (justified), the past participle of 'rechtfertigen' (to justify). So 'ungerechtfertigt' literally means 'not justified' or 'without good reason.'

'Ungerechtfertigt' (unjustified) is often used to describe negative statements or actions that lack a justification. Typical combinations are 'ungerechtfertigte Kritik' (unjustified criticism), 'ungerechtfertigte Vorwürfe' (unjustified accusations), or 'eine ungerechtfertigte Anschuldigung' (an unjustified accusation).

'berechtigt' and 'ungerechtfertigt' are opposites when it comes to reasons, criticism, worries, or decisions. 'berechtigt' says: there is a good and understandable reason. 'ungerechtfertigt' says: there is no sufficient reason, so something seems unfair or inappropriate. 'berechtigt' can also mean a right or permission, but in this contrast it is mainly about whether something is well-founded.
