ensimmäisiä
Ensimmäisiä is a Finnish word that functions primarily as the plural partitive form of the adjective ensimmäinen, meaning "first." It is used to refer to multiple items considered to be the initial ones within a larger set, especially when the exact number is indefinite or the emphasis is on the early stage rather than on count. In practice, ensimmäisiä modifies a noun in the partitive case: for example, ensimmäisiä kysymyksiä (some first questions), ensimmäisiä vaiheita (early stages), or ensimmäisiä kokemuksia (first experiences). The corresponding nominative plural is ensimmäiset, while the partitive plural is ensimmäisiä. While most often it appears as an adjective, the form can also function as a noun in literary or journalistic contexts to denote "the firsts" as a group.
Usage notes: The partitive expresses indefiniteness or non-totality, so ensimmäisiä is common in descriptions of sequences,
