March in Italian can be translated in two different ways depending on the meaning of 'march' that you are looking for. The month of March is translated into Marzo in Italian, whilst the verb 'to march' is written as marciare in the infinitive form, but can obviously relate to various conjugations of the verb.
Marzo, as in the third month of our modern calendar, relates to the Latin word for the god of war Mars (Martius) and was actually the first of the original ten months of the Roman calendar that was purportedly invented by Romulus, the founder of Rome around 753 BC.
The verb marciare is thought to derive from the same root as the French Marcher, with one possible origin being sourced from the word for 'confine'; as in to walk from one confine or border to another. March as a noun can be written as 'marcia' in Italian, with it's IPA transcription as /'marʧa/.
