Companion or leader
Kaid is a variant of the Arabic name Qaid, which traditionally refers to a leader, commander, or companion. In some contexts, it is also viewed as a modern phonetic spelling of the Gaelic-origin name Cade, meaning round or gentle. Its usage in the US is often a contemporary stylistic choice, blending traditional roots with a sleek, modern sound.
