drének
Drének is a term that can refer to several distinct concepts depending on the context. In some Slavic languages, such as Czech and Slovak, "drén" refers to the cornel tree (Cornus mas), also known as the European cornel or Cornelian cherry. This is a small deciduous tree or shrub prized for its early spring blossoms, tart red fruit, and durable wood. The fruit has been used in traditional medicine and for making jams, jellies, and liqueurs. The wood is hard and has historically been used for tool handles, small wooden objects, and even as a material for musical instruments like violins.
In other contexts, "drének" might be a misspelling or a regional variation of a different word entirely.
