Etymology Origin:
Derived from Latin substantiare ("to give substance"), the word combines sub- (suggesting support) + stantia ("substance" or "standing"). It evolved through Medieval Latin and entered English in the 17th century, originally tied to philosophical debates about material existence. The modern sense of "providing proof" reflects the idea of grounding claims in tangible evidence.
