Archaic Origins of Common Words

The words you mentioned, such as "чёлка" (bangs), "устный" (oral), "напёрсток" (thimble), "очки" (glasses), "узник" (prisoner), "ведьма" (witch), "медведь" (bear), "лягушка" (frog), "боровик" (porcini mushroom), and "колобок" (doughnut-shaped bun), have archaic origins. These words can be traced back to older forms of the Russian language or to words that were commonly used in the past.

Чёлка (bangs) is derived from the archaic word "чело" (forehead) [[1]]. Устный (oral) comes from the archaic word "уста" (mouth) [[2]]. Напёрсток (thimble) is derived from the archaic word "пёрст" (finger) [[3]]. Очки (glasses) can be traced back to the archaic word "очи" (eyes) [[4]]. Узник (prisoner) comes from the archaic word "узы" (bonds) [[5]]. Ведьма (witch) is derived from the archaic word "ведь" (knowing) [[6]]. Медведь (bear) can be traced back to the archaic word "медведица" (she-bear) [[7]]. Лягушка (frog) comes from the archaic word "ляга" (swamp) and "нога" (leg) [[8]]. Боровик (porcini mushroom) is derived from the archaic word "бор" (forest) [[9]]. Колобок (doughnut-shaped bun) can be traced back to the archaic word "колоб" (round loaf of bread) [[10]].

These words have survived in the Russian language, even though their original meanings or forms may have changed over time. They provide a glimpse into the linguistic history of the Russian language and the cultural context in which they were used.
