operatsioonilisi

Operatsioonilisi is an Estonian inflected form of the adjective operatsiooniline, meaning "operational" or "related to operation." The adjective derives from the noun operatsioon (operation) and is used to describe things connected with how systems or activities run and function. In Estonian, adjectives decline for number and case, and the ending -ilisi marks a plural form used with nouns in certain oblique cases.

This form is not a separate lexical item but a grammatical variant of the same adjective. It typically appears in sentences where the modified noun is in a case such as the genitive plural or partitive plural. For example, operatsiooniliste omaduste kirjeldus describes the description of operational properties, and operatsiooniliste protsesside kirjeldused refer to descriptions of operational processes. The exact case and degree of form can vary with the sentence structure and the noun it accompanies.

In usage, operatsioonilisi is common in technical, logistical, and organizational writing, where distinctions between operations, processes, and functions are important. It helps to keep the focus on aspects that pertain to execution, functioning, or performance rather than to the design or theory alone. Contexts may also contrast operatsioonilisi with closely related terms such as operatiivne (operative or operational) and operatsioon (operation), reflecting nuanced differences in how “operational” is applied in Estonian discourse.
