Forms
aequālis (neuter aequāle, comparative aequālior, superlative aequālissimus, adverb aequāliter); third-declension two-termination adjective[1]
Etymology
It is from Latin aequus (“level, equal”) + -ālis.[2][3][4]
Earliest recorded meaning
Ennius, in a tragedy, has a speaker fear the girls of the same age.[2] Köbler dates Ennius 204–169 BC.[5]
Semantic evolution
Its early sense was of the same age, coeval, and as a noun a companion of one's own age or a contemporary, as Cicero uses it in the Brutus.[2][6] It also meant equal in size, amount or duration, as Cato's equal maniples, and symmetrical.[2] From there it meant equal in status or comparable in quality, level or even of a surface, and uniform or regular in texture, style or character: Horace says nothing was consistent in a certain man.[2] Applied to law it meant applying to all alike, as Cicero's equal right of the law.[2] The Vulgate uses it of Christ making himself equal to God.[7]
In medieval Latin it also meant level, smooth and straight, and as a noun a peer.[8][9] English equal is recorded in the late 14th century.[4]
