groundless

This term describes a claim or fear that lacks a factual foundation, evoking the image of a building without a base that cannot stand. It carries a strong connotation of invalidity and is frequently used in legal, formal, or argumentative contexts to dismiss an accusation as completely fabricated or illogical. While similar to words like baseless, groundless often emphasizes the absence of a starting point or a justifying reason. It is typically used to describe abstract concepts such as suspicions, rumors, or fears rather than physical objects.
