substance: substance: [13] Latin substantia denoted the ‘essence’ of something. Derived from the present participle of substāre ‘be present’, a compound verb formed from the prefix sub- ‘under’ and stāre ‘stand’ (a relative of English stand), it was virtually a loan-translation of Greek hupóstasis ‘substance, existence, essence’, which likewise was formed from elements meaning literally ‘under’ and ‘stand’. The word’s ultimate etymological meaning is thus ‘that which underlies or is the essence of something’.

substance (n.): c. 1300, "essential nature, real or essential part," from Old French sustance, substance "goods, possessions; nature, composition" (12c.), from Latin substantia "being, essence, material," from substans, present participle of substare "stand firm, stand or be under, be present," from sub "up to, under" (see sub-) + stare "to stand," from PIE root *sta- "to stand" (see stet). Latin substantia translates Greek ousia "that which is one's own, one's substance or property; the being, essence, or nature of anything." Meaning "any kind of corporeal matter" is first attested mid-14c. Sense of "the matter of a study, discourse, etc." first recorded late 14c.
