What is the meaning of the name Ku ?

The baby name Ku is a Male name , 1 syllables long and is pronounced koo (IPA: /kuː/ or /ku/; approximate Korean/Japanese [ku]; Mandarin varies by character).

Ku is Chinese, Hawaiian, Japanese, Korean in Origin.

Ku is a compact cross‑cultural name with distinct roots. In Hawaiian, spelled Kū with a long vowel, it comes from the verb kū “to stand, be upright,” and names one of the four principal Hawaiian gods associated with war, fishing, and governance. As a given name it carries connotations of steadfastness and authority, used primarily for boys but sometimes unisex, and has seen renewed favor alongside the Hawaiian language revitalization.

Across East Asia, Ku often represents surnames in romanization. In Chinese it can render Gù (顾 ‘to look back’) or Gǔ (古/谷 ‘ancient; valley’) in Wade–Giles or Cantonese; as a given name it’s uncommon. In Korean, Ku/Gu (구) is a common surname, also spelled Koo. In Japanese, ku can map to 九 ‘nine,’ 区 ‘ward,’ or kū 空 ‘sky/void’; as a given name Ku is rare, though Kū/Kuu appear in modern usage. Variants: Ku, Kū, Kuu, Koo, Gu.
