An unassailable truth
Meaning
A fact or principle that is so strong and well-established that it cannot be doubted, attacked, or disproven.
Origin
The power of "an unassailable truth" lies in the sheer force of its individual words, fused to create an undeniable certainty. "Unassailable" descends from the Latin assilire, meaning "to leap upon," evolving through Old French assaillir to describe something impervious to attack. It conjures images of an impenetrable fortress, a stronghold that no enemy can breach. When paired with "truth," a concept humanity has grappled with since the dawn of reason, the phrase solidifies into a declaration of absolute, undeniable reality. It's not merely a fact; it's a fact so rigorously established, so profoundly self-evident, that any attempt to question it crumbles against its inherent strength.
Examples
- Despite initial skepticism, the scientific community eventually accepted global warming as an unassailable truth.
- For the defendant, the video footage provided an unassailable truth that exonerated him completely.
