täiendada

Täiendada is an Estonian verb meaning to improve, upgrade, or complete something by making it more thorough or up-to-date. It is used in contexts where increasing usefulness, accuracy, or value is the goal, such as developing skills, refining processes, updating equipment, or expanding curricula. The nuance is that the action adds missing elements or enhances quality rather than merely repairing something.

Common applications include improving personal abilities (täiendada oskusi), updating training programs or curricula (täiendada õppekava, täiendkoolitus), and upgrading technology (täiendada tarkvara or täiendada riistvara). In business and education, the verb often signals deliberate enhancement to align with new requirements, standards, or objectives.

Grammatically, täiendada is a regular verb of the -da class in Estonian. In the present tense, it forms as ma täiendan (I improve) and ta täiendab (he/she improves), among other person forms. The infinitive is täiendada. The past tense forms include täiendasin (I improved) and täiendas (he/she improved). The past participle is täiendatud (upgraded, completed) and the active participle täiendanud.
