tähendi

Tähendi is a grammatical case found in some Finnic languages, notably Estonian. It functions similarly to the partitive case in Finnish, but its usage and nuances differ. Tähendi typically expresses a part of something, an indefinite quantity, or an object of an action that is not fully completed or affects only a part of the object.

In Estonian, the tähendi is often formed by using the genitive singular or plural form of a noun, or by adding specific case endings. For example, it might be used with numerals to indicate a quantity, such as "kaks raamatut" (two books), where "raamatut" is in the tähendi. It can also be used with verbs that describe actions like eating, drinking, or seeing, implying that the action is not performed on the whole object. For instance, "ma söön leiba" (I am eating bread) uses the tähendi of "leib".

The precise application of the tähendi can be complex and depends on the specific verb, noun, and context. It is distinct from the accusative case, which typically denotes a whole or completed action. Understanding the tähendi is crucial for mastering the grammar of Estonian and related Finnic languages, as it conveys subtle but important distinctions in meaning. While similar in function to the partitive in Finnish, direct one-to-one mapping is not always accurate due to the evolution of each language.
