As all languages, Lithuanian surely has the plural, or daugiskaita (singular is called vienaskaita).

Let's see how each ending of nouns looks in plural.

In previous lessons, we have learned personal names and family words. Now we will make them plural:

vienas tėvas (one father) - du tėvai (two fathers)
vienas brolis (one brother) - trys broliai (three brothers)
vienas sūnus (one son) - keturi sūnūs (four sons)
viena mama (one mom) - penkios mamos (five mothers)
viena sesė (one sister) - šešios sesės (six sisters)
vienas Kazys - septyni Kaziai
viena Dalia - aštuonios Dalios
vienas vyras (one man) - devyni vyrai (nine men)
