The essive case is a grammatical case that indicates a state, role, capacity, or function. In Finnish, this case is typically marked by the essive suffix -na or -nä. It answers questions like "as what?" or "in what state?". For example, in the sentence "Hän työskentelee opettajana" (He/She works as a teacher), "opettajana" uses the essive case to signify the role of a teacher. Similarly, "Lapsi nukkui onnellisena" (The child slept happily) employs the essive to describe the state of happiness.

The essive case is distinct from other Finnish cases, such as the translative, which indicates a change of state or transformation. While both can involve a suffix like -na/-nä, the translative implies becoming something else, whereas the essive describes an ongoing condition or identity. The choice between -na and -nä depends on vowel harmony rules within the word. If the word's last vowel is front (e.g., ä, ö, y, i, e), the suffix -nä is used. If it's back (e.g., a, o, u), the suffix -na is used. This suffix can attach to nouns, pronouns, adjectives, and even participles to express their role or state in a sentence. The essive case is a fundamental aspect of Finnish grammar, enriching the language's ability to convey nuanced meanings about states and roles.
