I wonder why in all Romance languages the word "war" ("guerra", with their multiple intonations) is a term that comes from Germanic languages, and that no modern language resembles the Latin "bellum". In English it actually came from Old French, which in turn came from Frankish.
It seems to me particularly curious since "war" is a term so significant for Latin tradition, and also the contrary, "peace", is inherited in almost intact form in all Romance languages and even in English from the Latin "pax".
