Operatsiooni is the genitive singular form of the Estonian noun operatsioon, meaning operation. The word covers several senses in Estonian: a medical or surgical procedure, a military or strategic action, a mathematical or computational procedure, and a general undertaking or process.

Etymology and influence: operatsioon is a loanword that traces to Latin operatio, passing into Estonian via European languages such as French (operation) and German, among others. In Estonian usage it denotes a planned or performed action or procedure in various domains.

Usage and grammar: In standard Estonian, operatsioon refers to a procedure or action. Its genitive singular form operatsiooni is commonly used with modifiers and in phrases such as kirurgia operatsiooni ajal (during the surgical operation) or operatsiooni eesmärk (the purpose of the operation). Plural and other case forms use different endings, for example operatsioonid in nominative plural and operatsioonide in genitive plural. The term is also found in mathematical and computing contexts, where a similar notion is described by other terminology (for example, arve- või matemaatiline operatsioon varies by context).
