suletav

Suletav is an Estonian adjective derived from the verb sulgema, meaning to close. It describes something that can be closed or is designed to be closed, functioning as a property of objects, mechanisms, or interfaces. The term is used in everyday language as well as technical or formal registers to indicate closability.

In practice, suletav is applied to a range of nouns, including architectural elements, containers, and software or mechanical components. Examples include suletav uks (a door that can be closed), suletav aken (a window that can be closed), suletav kaas (a closable lid), suletav sahtel (a drawer that can be closed), and suletav dialoog (a dialog window that can be closed). It often appears in technical documentation, product specifications, and design discussions to specify functional requirements.

Morphology and usage: suletav is a participial adjective formed with the suffix -tav from the verb sulgema. It behaves like other Estonian adjectives and is declined for number and cases, typically preceding the noun it modifies (suletav uks, suletava ukse, suletavaks uks, etc.). It can be used attributively and, in some contexts, predicatively where Estonian supports adjectival predicates.

Etymology: the form comes from sulgema (to close) combined with the participial suffix -tav, a common construction in Estonian to indicate potential or capability.
