Granted I am not going be some "lefty" dude saying ohh because of that we should allow the whole world in but nevertheless the Eurasian continent is fascinating to study and Maltese is basically Arabic to a extent but Latin
It is somewhat a synthesis between italic-sicilian and a very non-standard arabic (even for its time as linguists have not been able to trace and assign morphology to any other type of Arabic be it koranic, classical or one of the regional dialects today).
Most of the (common-used) vocab is apparently italic/sicilian for example...and about 1 third is arabic-based.
These ratios might have changed over time of course since the retaking of malta startingwith raids by Norman dukes of Sicily (thats a long story in itself) after the earlier moorish conquest of it (referred to in "the sicilian scene" with walken in that movie hehe).
I dont have much knowlege on Maltese people and Malta itself past one English teacher I had in primary school who was born there (but she was English as can be tbh).
