Koah

Koah is a modern spelling often chosen in relation to Koa. Hawaiian koa can refer to bravery or a warrior and is also the name of a tree, but the added h does not make Koah an independently established Hawaiian word. Other proposed links, including Hebrew strength, depend on a family’s intended source rather than a universal meaning for this spelling.

Koah resembles both Koa and Noah on the page while keeping a compact two-syllable sound. Parents who specifically want the Hawaiian name may prefer Koa, whose language form and meanings are clearer. Families choosing Koah for its appearance can still explain their intended connection without blending unrelated languages into one compound translation.
