rõngaks

Rõngaks is the translative form of the Estonian noun rõngas, which means ring or hoop. In Estonian grammar, the translative case, marked by the suffix -ks, expresses a change of state or a new role. Therefore, rõngaks denotes something becoming a ring or being used as a ring, rather than existing as one in the nominative form.

As a case form, rõngaks does not constitute a separate word with its own lexical entry; it is the inflected form used in sentences to convey transformation or function. Its use is primarily grammatical, but it can appear in contexts such as descriptions of manufacturing or crafting (where a material is shaped into a ring) or in technical writing where a concept is to be described as having the form or role of a ring. In mathematical or geometrical discussions, the base word rángas is often used in other cases, while rõngaks would appear in constructions that emphasize becoming or being designated as a ring.

Common notes: the translative form follows regular Estonian inflection patterns, with the stem undergoings of the final consonant and vowel adjustments typical for -ks endings. The term highlights how Estonian expresses transformation or designation through case endings rather than using separate words.
