neljas

Neljas is the Estonian word for "the fourth." It is used as an ordinal numeral to indicate sequence and functions as an adjective that modifies a noun, agreeing with its case and number.

In standard Estonian, ordinal numbers are declined to match the noun they describe. Common forms for neljas include neljas (nominative singular), neljanda (genitive singular), and neljandat (partitive singular). Examples: Neljas päev means the fourth day; Neljanda päeva jooksul means during the fourth day.

Neljas is routinely used to denote position within calendars, schedules, rankings, and other ordered lists. It can appear in phrases such as neljas korrus (the fourth floor) or neljas nädal (the fourth week). Like other Estonian ordinals, it is part of a broader system that includes esimene (first) and kolmas (third), among others.

Outside grammatical use, neljas may also appear in proper names or stylistic titles in Estonian contexts, though its primary function remains linguistic—marking order. The word is a standard element of Estonian language education and everyday speech when describing sequence.
