Aktiivseid

Aktiivseid is the partitive plural form of the Estonian adjective aktiivne, meaning active. It is not a stand-alone noun but appears in noun phrases to describe an indefinite or partially considered group of nouns, for example aktiivseid inimesi (active people) or aktiivseid tegusid (active deeds).

In Estonian grammar, adjectives agree with the nouns they modify in number and case. The partitive plural ending -seid is used when the object is viewed in part, or when the reference is indefinite, or after verbs that require the partitive. The nominative plural form is aktiivsed, while the partitive singular form is aktiivset and the genitive singular form is aktiivse. Thus, aktiivseid specifically marks a plural, non-fully-completed set in the partitive sense.

Usage and examples: Aktiivseid inimeste rühmi may appear in discussions about social groups or participation. Common constructions include sentences such as “Vaatasime aktiivseid inimesi pargis” (We observed active people in the park) or “Tehtud on palju aktiivseid tegusid” (Many active deeds have been accomplished). In written Estonian, the word often appears within longer phrases rather than as a standalone term.
