Sesuatu

Sesuatu is a word used in Indonesian and Malay that functions as an indefinite pronoun or determiner, roughly meaning “something” or “a certain thing.” It is formed from the prefix se- attached to the root word suatu, a combination that conveys indefiniteness or generality. The term appears in standard written language as well as in everyday speech, though its exact nuance can vary by context and register.

In use, sesuatu refers to an unnamed object or matter. It can serve as the subject or object of a sentence, for example: “Ada sesuatu yang menarik di sini.” It can also appear in phrases like “sesuatu hal” or “sesuatu perkara” to denote a matter of unspecified nature. The word is versatile and often found in formal or literary contexts, where speakers might prefer it to a more specific noun.

Differences from related forms are notable. While suatuan by itself is used in fixed expressions such as “suatu hari” (one day) or “suatu ketika” (at some time), sesuatu tends to emphasize an unspecified thing rather than a temporal sense. Overall, sesuatu is a neutral, standard element in Indonesian and Malay grammar, suitable for reference in dictionaries, grammar guides, and encyclopedic text. Related terms include suata and apa-apa as alternatives for more casual or varied indefinite references.
