"Passed on" is a common phrase used to describe the act of someone dying. However, there are several other synonyms that could be used instead of "passed on". For example, someone could say "passed away", "passed on to the afterlife", "expired", "left this world", or "transitioned". Each of these phrases convey the same meaning and display respect to the person who has departed. It is important to choose words carefully when discussing death as it is a sensitive topic. While it may be uncomfortable to talk about, using appropriate language can help to ease the pain and show compassion to those who are grieving.
