Tasandada

Tasandada is an Estonian verb meaning to level or flatten a surface or to make something even. The word is built from the noun tasand, meaning level or plane, with the infinitive suffix -da. As a transitive verb, tasandada requires a direct object and is used to describe actions that produce evenness, such as leveling a ground surface, smoothing a roadbed, or equalizing a slope. It is also used in broader, non-physical senses to denote making conditions more even or fair, for example leveling the playing field.

In practical contexts, tasandada appears in fields such as construction, surveying, and civil engineering, where leveling work is routine. It can also be encountered in geology or geography when describing processes that reduce variation in elevation. Because it is a common verb, tasandada forms part of standard Estonian verb conjugation and follows the regular patterns of Estonian mood, tense, and aspect.

The related noun tasand means level, flat surface, or plane, and the adjective tasandlik describes something flat or even. The term is widely used in technical writing as well as everyday speech to convey the idea of smoothing irregularities and achieving uniformity.
