The phrase "passed away" is a common way to describe the death of a person. However, there are several other synonyms that can be used to describe the same thing. Some common and more formal phrases are "deceased," "expired," "departed," "gone," and "lost." Other informal but more gentle terms include "passed on," "passed over," "gone to a better place," and "went home." These synonyms provide a range of expressions that can help to convey a sense of respect, compassion, and sympathy towards the departed and the bereaved family and friends.
