Sisaldavaks

Sisaldavaks is an Estonian linguistic term describing a specific inflected form of the adjective sisaldav, meaning “containing.” It represents the translative singular and is used to express a role, state, or purpose, roughly equivalent in English to “for containing” or “to be used for containing.” The form is created by attaching the translative suffix -aks to the stem sisaldav, producing sisaldavaks. In Estonian grammar, the translative case signals a shift toward a new state or function and is commonly used to designate purpose or designation in phrases and noun–adjective sequences.

The word is primarily encountered in linguistic descriptions, grammar handbooks, or prescriptive examples illustrating inflection. It is not a common everyday lexical item. In ordinary speech or writing, one would usually express the idea with a different construction, such as a phrase indicating purpose rather than relying on a dedicated form like sisaldavaks.

Etymology and related forms: sisaldavaks is built from the verb sisaldama (“to include”) via the participial adjective sisaldav (“containing”) plus the translative suffix -aks. Related forms include sisaldav (“containing”) and the base verb sisaldama, as well as other translative forms such as -ks on nouns and adjectives. The form illustrates how Estonian uses translative endings to express purpose or designation in inflected phrases.
