Arabic origin of Portuguse word 'alcaide'

No, it's from Arabic al-qadi, the judge, which is not from the same root as al-qa'ida.

Kadi is also a colloquial term for judge in German (at least in Austria).

#2 -- That may come through Turkish. The Turks borrowed the Arabic word.

#3 -- Yes, I think so too.

This is what I found

alcayde, commander or governor of a Moorish or Spanish or Portuguese fortress; warden or keeper of a Moorish or Spanish or Portuguese prison. VinnyD, my research supports your etimology. It's Arabic and from what I read it dates back to 1502.

Thank you everyone.
