Let’s take a look at some of the other etymologies. Polish kwiecień and Ukrainian kvíten’ come from a Slavic word meaning “to blossom” (and are false friends of Czech květen, which means “May”). Belarusian krasavík is derived either from krasa, “beauty”, or kraska, “field flower”. Czech duben is derived from dub, “oak”. Croatian travanj is related to trava, meaning “grass”.

Finnish huhtikuu comes from huhta (“cleared field in slash-and-burn cultivation”) + kuu (“month”). Voro mahlakuu means “juice/sap month”. Karelian sulaku is derived from sula, “molten; not having ice cover”. Northern Sami cuoŋománnu means “snow crust month”.

Lithuanian balandis means “dove” (a bird). Turkish nisan comes from Assyrian nisannu, “beginning”.
