Kusi

Kusi is a term with several uses. The most widely attested meaning comes from the Quechua language, where kusi means “to be happy” or “happiness.” In Quechua, it functions as both an adjective meaning joyful and a noun denoting happiness. The word appears in everyday speech, traditional songs, and various expressions that emphasize well-being and positive emotion.

Beyond its linguistic sense, Kusi also appears as a personal name or surname in different communities, and it may be used in contemporary branding or as part of proper nouns. Because the term has multiple independent uses in different languages and cultures, its meaning can vary with context, and not all uses are connected to the Quechua concept of happiness.

Kusi is sometimes encountered in linguistic studies as an example of a short, monosyllabic word from Andean languages that has broader cultural resonance. When appearing in texts, the specific meaning should be inferred from surrounding context to determine whether it references the Quechua concept of happiness, a personal name, or another unrelated use.
