Mishneh Torah, Torah Study
A student is forbidden to call his master by name even out of his presence, provided the name be of note that whosoever hears it will know that it is he; neither should he mention his name in his presence, nor even call others whose name are identical with the name of his master, even as one does with respect to the name of his father; but he should always refer to them with a pseudonym even after their demise. He must not salute his master or return salutation in a manner companions give and return among themselves. The manner to salute a master is to bow before him and say to him in tones of awe and respect: "Peace be unto thee, my master!" If his master saluted him first, he should answer him: "Peace be unto thee, my lord and my teacher.5Sanhedrin, 100a; Kiddushin, 31b and 32a; Berakot, 28b. C. G.
