''Name
The city's name is the same as a Ukrainian name for Artemisia vulgaris, mugwort or common wormwood, which is Ukrainian: чорнобиль, translit. chornóbyl’ (or more commonly Ukrainian: полин звичайний, translit. polýn zvycháynyy, lit. 'common artemisia').[3] The name is inherited from Proto-Slavic *čьrnobylъ or Proto-Slavic *čьrnobyl, a compound of Proto-Slavic *čьrnъ 'black' + Proto-Slavic *bylь 'grass', the parts related to Ukrainian: чорний, translit. chórnyy, lit. 'black' and Ukrainian: било, translit. byló, lit. 'stalk', so named in distinction to the lighter-stemmed wormwood A. absinthium.[3] ''
