The dynasty of the lamdanishe brisker

Hi fellow lamdanim !!! To my knowledge the rambam wrote his pirush on mishnayos in arabic!! Not aramaic , and. I dont beleive that is a very heilige launguage , also harav hirsch wrote his sefer in german , but efsher lidchok that it has kedushas yiddish! וצ״ע לדינא .
