What is the meaning of the name Achates ?

The baby name Achates is a Male name , 3 syllables long and is pronounced uh-KAY-teez (IPA: /əˈkeɪtiːz/).

Achates is Greek, Latin in Origin.

Achates is the Latin form (from Greek Achátēs, Αχάτης) of a classical name linked to the Sicilian river Achates, source-name of the gemstone agate. As a personal name it carries no defined ancient meaning, though it can be read loosely as “agate” or “of the Achates.” In English tradition it is best known through Virgil’s epithet “fidus Achates,” so the name has come to connote steadfast loyalty and devoted friendship.

Usage is almost entirely literary: Achates appears in Virgil’s Aeneid as Aeneas’s faithful companion, and the phrase circulated in Renaissance and later European letters. As a given name it surfaced sporadically among humanists and classicists and remains exceedingly rare today. Variants and related forms include Greek Achátēs (Αχάτης), Latin Achates, and the Italian toponym/personal form Acate; the English word agate is etymologically related but not a true variant. Diminutives are uncommon; the name suits those seeking an erudite classical choice.
