teadma

Etymology
From, probably derived from (modern Estonian ). In this case the verb seems to have originally meant ’to know the way’. Cognates include 🇨🇬, 🇨🇬, 🇨🇬; 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

The standard language stem tead- originates from dialects, where the long vowel has diphthongized, which results in this word instead of the expected *teedma. Alternatively, the strong grade stem results from analogy with verb forms formed from weak grade (mostly present tense, *teedät > *teeat > "you know").

Verb

 * 1)  to know to have information, knowledge about something, to be aware of something
 * 2)  to know to be acquainted or familiar with
