@krazy0flaka,
I don't know how you came up with "excelsum simuli", but it certainly
doesn't mean "excel together". Excelsum is a height or a lofty place. Maybe
you meant
simul (at the same time) instead of
"simuli"?
In any case, I would translate it:
Una Excellite
Una --> (adv.) together, as one
Excellite --> excel
That other sentence I'll have to think about a bit.
Back later.
