1). What have you already done?

2). feast.

2.1). Русский: Нет, но это частично верно, так как пир состоит из еды. Пир это праздничное обильное застолье. А сама еда это то, что мы принимаем на пире.

Английский: No, but this is partially true, as the feast consists of food. A feast is a festive plentiful feast. And the food  is what we eat at the feast.

4). When I was in history at school, we talked about a feast. A feast is a festive feast, like a great dinner party. They were arranged mainly for the holidays. A treat with plentiful food and drinks, all this could be seen there. So often there were dances, songs, and jokes. There were royal feasts, and with them the feasts of the gods, as some claim.
