- constant (adj.) late 14c., "steadfast, resolute; patient, unshakable; fixed or firm in mind," from Old French constant (14c.) or directly from Latin constantem (nominative constans) "standing firm, stable, steadfast, faithful," present participle of constare "to stand together," from assimilated form of com "with, together" (see con-) + stare "to stand," from PIE root *sta- "to stand, make or be firm."
- constant (n.) 1832 in mathematics and physics, "a quantity which is assumed to be invariable throughout," from constant (adj.), which is attested from 1753 in mathematics. The general sense "that which is not subject to change" (1856) is a figurative extension from this.
