Etymology

It is the present participle of cōnstō “to stand together, stand firm”, used as an adjective.[2][1][3]

Earliest recorded meaning

Köbler's first source is Lucretius, whom he dates 96–55 BC, and Lucretius says honey is of a firmer nature.[4][5]

Semantic evolution

It meant standing firm, stable, of firm consistency, as Lucretius' honey and in Horace, and in Cicero mentally settled, steady.[2][5] In the Rhetorica ad Herennium it meant definite, and unchanging.[2] In Cicero it meant resolute, steadfast in principles, consistent, loyal, constant, and of things self-consistent.[2]

In Ecclesiastical Latin it meant steady, firm, constant.[6] English constant came in the late 14th century, “steadfast”, and as a mathematical noun in 1832.[3] As a name, Cōnstāns was borne by a son of Constantine.[5]
