Jaamasid

Jaamasid is the Estonian word that functions as the partitive plural form of jaamad, meaning stations. It is used when the object of a sentence is indefinite, when multiple stations are involved, or when the exact number is not specified.

Formation and function: The base word jaam means "station." Its plural nominative is jaamad. The partitive plural form jaamasid is used with verbs or numerals that require the partitive case, for example in phrases such as mitmeid jaamasid (several stations) or ma nägin jaamasid (I saw stations).

Usage: In travel writing, transportation contexts, and everyday speech, jaamasid appears in constructions that emphasize the existence or experience of stations rather than a defined set. It contrasts with jaamad (nominative plural), when the number is fixed or the whole set is being referred to, and with jaama (genitive singular) or jaamade (genitive plural) in other grammatical roles.
