Proto-Finnic is the common ancestor of the Finnic languages, which include the national languages Finnish and Estonian. Proto-Finnic is not attested in any texts, but has been reconstructed by linguists.
Proto-Finnic is conjugated in several moods, 2 tenses, 2 numbers (singular and plural), and three persons. There is also an impersonal form, like in today's FInnish for example.
