teisest

teisest is an Estonian adjective form meaning "from another" or "of a different one" when used in the elative case. It is the elative singular form of the word teine, which generally translates as "other" or "different" and can also sometimes convey the sense of "the other one" or "the second." In Estonian, adjectives agree with the noun they modify in case, number, and gender, so teisest accompanies a noun in the elative case.

The primary use of teisest is to indicate origin or source from a different item, person, place, or thing. It commonly occurs with nouns in the elative: teisest linnast (from another city), teisest allikast (from another source), teisest inimestest (from other people). It can also appear in broader phrases that describe an alternative perspective or source, always linking to the elative form of the noun.

Etymologically, teisest is derived from teine, the Estonian word for "other" or "second," with inflectional endings applied to form the elative case. This contrasts with teist (the partitive form used with verbs that require partitive objects) and teise (the genitive form), which serve different grammatical needs.

In usage, teisest is a productive modifier for expressing comparison of origin or choice between options, and it often appears in factual or descriptive prose. It should not be confused with other case forms of teine, such as teise (genitive) or teist (partitive), which have distinct grammatical functions.

Example sentences:

- Ta tuli teisest linnast. (He came from another city.)

- Uuringu tulemused pärinevad teisest allikast. (The study results originate from another source.)
