- It is forbidden to call one’s parents by name, even when they are not present. Instead one should say, אבי מורי, “My father, my master” (Turand Shulchan Aruch, YD 240:1). In situations where the appellation “My father, my master” is not appropriate, one may say “Father so-and-so,” using the father’s name, since this is also a respectful wording (Aruch Hashulchan, YD 240:15).
2. One who wishes to address a person who has the same name as his father or mother — (a) if it is an uncommon name, and it is in the presence of the parent, he should not call out using that name, because it appears as though he is calling out to his parent; (b) if it is a common name, and the parent is not present, one may call the other fellow using the name of the parent; (c) if it is a common name, and the parent is present, or if it is an uncommon name but the parent is not present—some authorities forbid using the name and others allow it (ibid.).
