tasandid

Tasandid is an Estonian plural noun meaning levels, tiers or layers within a multi-layered structure. The word comes from tasand, which denotes a flat surface, a level or a step in a sequence. In everyday language tasandid is used both literally and figuratively to refer to different strata within a system.

Common usages span several domains. In geography or geology, tasandid may describe geological layers or strata. In information technology and software design, tasandid can refer to abstraction layers or service levels within an architecture. In education and training contexts, tasandid can denote levels of achievement, difficulty or progression within a curriculum or program.

Usage notes: the precise meaning depends on context; tasandid is plural and can pair with adjectives (erinevad, kõrgemad, erinevad tasandid). Some dictionaries simply define tasandid as "levels" or "tiers". In formal writing, it is advisable to specify the domain (geoloogilised tasandid, tarkvaraarhitektuuri tasandid).

See also: tasand, kiht, tase. References: Estonian dictionaries and corpora give the common meaning as levels or layers; the term is widely used in technical and academic language but not limited to one field.
