unfounded
Not supported by facts, proof, or good reasons.
When something is unfounded, it means it has no basis in fact or evidence. An unfounded rumor spreads around school even though there's nothing true supporting it. An unfounded accusation blames someone without any proof they actually did anything wrong.
Think of it like building a house: if you want a sturdy structure, you need a solid foundation. An unfounded claim is like a house built on air. It might sound convincing when someone first says it, but when you look for evidence or facts underneath, there's nothing there to support it.
You might hear someone say their fears were unfounded after worrying about something that turned out fine. Maybe you were nervous about a difficult test, but after studying hard, you discovered your anxiety was unfounded because you knew the material well. Or perhaps you worried a friend was angry with you, but those fears proved unfounded when they greeted you warmly the next day.
The word reminds us to ask important questions: What evidence supports this claim? Where did this information come from? Just because something sounds plausible or gets repeated doesn't make it true. When you hear a dramatic story or accusation, it's worth checking whether it's founded on facts or completely unfounded.
