Calling a parent by name

Hi,

One may not call his parents by their personal names; instead, one should say "My father/mother, my teacher." This continues even after their deaths.

One may use a parent's name when talking about, or to, someone else who has the same name - but only if the name is common and if the parent is not present. If the parent is present, some authorities will not allow the use of the parent's name, despite its commonness.

(Code of Jewish Law Yoreh Deah 240:2; Shach Yoreh Deah 240:3)

Have a great day,
Mordechai
