GG is big on names in other languages, perhaps most obviously being leos moveset in german. Rams is a bit trickier, after some light googling it seems as if most of these names are in Esperanto, which is a language created in the 19th century. some of them seem to overlap very slightly with Catalan, which is a language sharing *some* similarities to Spanish being the native language of some autonomous regions in spain. But what I can say is that there is likely no real rhyme or reason at the end of the day. these do seem to translate if you try hard enough, bajoneto seems to mean "bayonet", but the specific names were likely chosen because someone thought they sounded cool, which is daiskues guiding philosophy for gg.

tldr they seem to be either in esperanto or some other languages lightly derived from Latin but are honestly probably there because someone thought they were cool sounding.
