Was hoping it would mean something "Great" to give us a bit of hope,
But from my research so far, in Spanish it means 'Nice'
And in Polish it means 'may' which I guess One could take as he May keep us up in May (?)
From Arabic roots, its meaning is 'splendid'
In Korean, maja would be the unconjugated and informal form of the verb 'to be correct' or 'to agree' with something. To be polite or formal when talking with elders you would add a yo at the end and say majayo.
