üksteiselt

Üksteiselt is not a standard lexical item in Estonian dictionaries and is not widely attested in formal language contexts. In standard Estonian, there is no established definition for a word by this exact form, and its appearance in texts is typically considered nonstandard, dialectal, or potentially a misspelling or coinage. Because of the lack of authoritative usage, there is no agreed meaning or canonical grammar associated with üksteiselt.

If the form is encountered, it is usually treated as an experimental or mistaken construction rather than a recognized word. Its apparent resemblance to a compound built from the numeral üks (one) and suffixes found in Estonian morphology does not yield a documented semantic path, and no reliable corpus evidence supports a fixed sense for üksteiselt. Consequently, most editors would flag it as unclear or incorrect in formal writing.

In standard Estonian, writers seeking to express sequential or one-by-one action should use established expressions instead. Common, well-attested alternatives include ühekaupa (one by one), järjest (in order, successively), järk-järgult (gradually, step by step), and vaheldumisi (alternately). For mutual or reciprocal relations, other clearly defined forms such as üksteisele or omavahel are used depending on the intended meaning. Until üksteiselt gains recognized status in dictionaries or corpora, it remains a nonstandard form rather than a reliable part of Estonian vocabulary.
