Origin: Latin, Welsh, English
Meaning: from Latin Martius, named after the Roman god of wars Mars, whose name comes from Latin mas meaning “male” or “manly”.
I’ve also seen it listed as a Welsh form of Mark (pronounced the same) which also comes from Mars.
As well as being the third month of the year, march is also a word, referring to the act of marching, to walk in a measured and deliberate manner.
March also comes from Old French marche meaning “boundary”, referring to a tract of land along a border of a country. In Britian, the Marches refer to a belt of land on the boundary with Wales.
