Kuud

Kuud is a word in Estonian that functions as the plural form of kuu, meaning both “the Moon” and “months” depending on context. When referring to the Moon, the word is written as Kuu, a proper noun for Earth’s natural satellite; for example, Kuu paistab öötaevas means “The Moon shines in the night sky.” When referring to units of time, kuud denotes months, as in kaks kuud (two months) or kolm kuud (three months). The form is also used across grammatical cases in the plural.

Etymology and related forms: Kuud is the plural nominative of kuu. It is cognate with the Finnish kuu; both derive from a common Finnic root, reflecting their shared linguistic heritage.

Usage notes: In Estonian, nouns decline for cases, and kuud follows the standard plural pattern for kuu. The celestial sense typically retains capitalization (Kuu), while the plural meaning (months) is written in lowercase unless at the start of a sentence.
