unfounded
Without an understandable reason, proof, or justification; not based on facts.
Die Sorge, dass das neue System nicht funktionieren würde, erwies sich als völlig unbegründet.
The concern that the new system would not work proved to be completely unfounded.
The word consists of the prefix 'un-', which expresses negation, and 'begründet' (justified/founded). 'Begründet' is derived from the noun 'der Grund' (the reason). So something that is 'unbegründet' (unfounded) literally has 'no reason'.
Deine Kritik ist völlig unbegründet, denn du kennst nicht alle Fakten.
Your criticism is completely unfounded because you don't know all the facts.
'Unbegründet' (unfounded) is often used predicatively with verbs like 'sein' (to be), 'bleiben' (to remain), or 'sich erweisen als' (to prove to be). This construction emphasizes that an assumption or concern has turned out to be false.
Seine Angst vor der Prüfung war unbegründet.
His fear of the exam was unfounded.
Common nouns described as 'unbegründet' (unfounded) include 'Sorge' (concern), 'Angst' (fear), 'Kritik' (criticism), or 'Vorwurf' (accusation). The word is often intensified by adverbs like 'völlig' (completely) or 'gänzlich' (entirely).
Der Vorwurf gegen ihn war gänzlich unbegründet.
The accusation against him was entirely unfounded.
founded / based
'gegründet' and 'unbegründet' are opposites here when talking about reasons or evidence. 'Gegründet auf' means that something has a basis or justification. 'Unbegründet' means that an accusation, a worry, or an opinion has no understandable reason. The words can be confusing because 'gegründet' can also mean that a company has been founded. But 'unbegründet' is not about companies; it is about whether something is well-founded or not.
Die Sorge der Eltern war unbegründet, denn das Kind kam pünktlich nach Hause.
The parents' worry was unfounded, because the child came home on time.
