arvamusest

Arvamusest is a grammatical form in the Estonian language. It is the elative singular form of the noun arvamus, which means "opinion." The elative case indicates origin or basis, so arvamusest translates roughly as "from an opinion" or "on the basis of an opinion." This form is used in sentences to attribute a claim or conclusion to a particular opinion or source.

In Estonian, the elative case is created by adding the suffix -st to the base stem. Arvamusest therefore signals that what follows or what is being referred to stems from or is derived from an opinion. The term is most commonly encountered in formal, analytical, or academic contexts, such as legal texts, policy discussions, or scholarly writing, where speakers transmit that a statement is grounded in a particular viewpoint.

Usage can appear in combinations like arvamusest lähtudes, meaning "based on an opinion" or "taking into account the opinion." This construction is used to connect reasoning to the underlying viewpoint being cited. While arvamusest itself is the elative form, it is part of a broader system of Estonian case forms that link statements to their sources.
