What is the meaning of the name Kasius ?

Kasius is Latin in Origin.

Kasius (pronounced KAY-see-us or KAH-see-us) is a modern re-spelling of Cassius/Kassius, drawing on both Latin and Greek strands. The Roman family name Cassius has uncertain roots, often linked to Latin cassus “empty, hollow,” while the Greek Kassios/Kasios referred to the cult of Zeus on Mount Kasios, yielding a sense of “of Mount Kasios.” The wider Cassius tradition spans the Roman Republic and Empire - borne by figures such as Gaius Cassius Longinus and the historian Cassius Dio - and later entered Christian usage through several saints.

Kasius itself is rare but emerges as a sleek contemporary variant. Related forms include Cassius, Casius, Kassius, and Cassian/Cassiano; Cassio (Italian/Portuguese) and Casio are cognate adaptations. Short forms Cas, Cass, Cash, and modern Kash also circulate. Feminine counterparts are Cassia and Kassia, the latter associated with the 9th-century Byzantine poet-saint. Meanings thus range from the Latin “hollow” cognomen to a Greek toponymic sense, giving Kasius classical depth with a distinctive twist.
