What difference does it make? If it makes someone have an easier time coping with the fact, I will used words that soften the blow.

Call me rude...I'll avoid euphemism and say "died."

Even more interesting is why do we have funerals, the dead can't see the honors we bestow on them?

I love to ask Dr. Google stuff like this, and Dr. Google fulfilled my request. [rfhr.com].

Of course that is from a funeral home. It says:

When a loved one dies, it can be challenging to cope with the loss. You may hear others say that your loved one “passed away” and wonder what that means. While “passed away” is a euphemism for death, many religions believe that a soul passes on into another realm after death. This is where the idea that someone “passed away” comes from.

Let’s look at what “passed away” and other euphemisms mean and what to say about the death of a loved one.

What Does “Passed Away” Mean?
We first see the term “passed away” appear in English writings of the 15th century. In the 1400s, the majority of individuals believed that the departing of the soul of a dead person was a literal physical event.

“Passing away” meant that the deceased person had begun their soul’s journey to heaven or hell. (1)

Why is “Passed Away” Used as a Euphemism for Death?
A euphemism is a way of saying something without coming out and saying it. People use euphemisms when they don’t want to say a word that might upset or offend someone else. The term “pass away” is one of the oldest euphemisms known in English.

Many individuals don’t like to think of death when thinking of a loved one who died because it sounds so final. They may say or want to hear others say “passed away” as a calmer and gentler way of talking about death.

They might also use or prefer other euphemisms for death, such as:

Left this world
Passed on
Sleeping
Gone from this world
In heaven
With the angels
Resting in peace
Finished their race
Done with their suffering
Dearly departed
However, for those who believe in an afterlife for the soul, these euphemisms are not just a saying to make the word “death” sound nicer. For those who believe in the soul and an afterlife, “passed away” is a literal description of what they think happens to a soul after death.

Do All Religions Believe in a Soul?
You may wonder which religions believe in a soul. But first, let’s define “religion.” According to Mark Stibich, Ph.D.,

“Religion is a set of organized beliefs, practices, and systems that most often relate to belief and worship of a controlling force such as a personal god or another supernatural being. While this is a basic definition, there are many different understandings of what religion is and not all religions are centered on a belief in a god, gods, or supernatural forces.

Religion often involves cultural beliefs, worldviews, texts, prophecies, revelations, and morals that have spiritual meaning to members of the particular faith, and it can encompass a range of practices including sermons, rituals, prayer, meditation, holy places, symbols, trances, and feasts.” (1)

With that definition in mind, many individuals have religious beliefs in the US. However, many belief systems are also eclectic and may or may not include belief in a soul or an afterlife.

For example, some religions include rituals or meditation but believe in an end to life when you die. Others may believe in a universal consciousness and that our soul becomes part of the universal consciousness at death. Atheists often feel that this life is over at death, and there is no more consciousness afterward.

What Do Different Religions Believe About a Soul?
According to new findings from Pew Research, most US citizens believe in a soul. In their 2021 study Views on the Afterlife, “Nearly three-quarters of U.S. adults say they believe in heaven.” Many religions in the US believe in some form of an afterlife for the soul.

Here are a few examples:

Islam
Muslims believe in angels and jinn (spirits). They also believe in the Day of Judgment, when everyone will be resurrected and judged according to their deeds. Many of the same prophets in the Muslim religion are the same prophets mentioned in the Old Testament of Christianity. In Islamic beliefs, after judgment, the righteous go to paradise. The Muslim holy book is the Quran.

Judaism
Jews believe in the immortality of the soul. They also believe in a messiah who will come to save them and usher in a time of peace. However, most Jews reject the Jesus of Christianity as the Messiah and are waiting for the Messiah to come. Jewish and Christian religions both honor the Old Testament in the Bible as a religious text. After death, Jews believe the soul goes to a place called Sheol until the Messiah comes. Their souls will resurrect at that time and go to heaven if they’ve obeyed the law well.

Christianity
Most Christians believe that when Jesus died on the cross and then resurrected back to life, he paid for the world’s sins in ways humans could never atone for themselves. Christians believe Jesus was God in the flesh, and their belief in his sacrifice on the cross brings their soul a rebirth into God’s family. After death, Christians believe their soul will pass on to live forever with God in heaven.

Hinduism
Hindus believe in reincarnation and karma. They believe that the soul is reborn into another body after death and that this cycle continues until they reach Nirvana (a state of perfect happiness). How a person is reborn depends on their karma (the good or bad deeds they’ve done in their past life). Karma is the idea that our actions have eternal consequences.

Buddhism
Buddhists believe in reincarnation and karma as well. However, they also believe in nirvana, a state of perfect peace while living on earth. They believe that you can attain nirvana through good deeds and living a moral life.

As you can see, there are many different major belief systems about what happens to our soul at death. Many other religions or belief systems have other beliefs about the soul or an afterlife.

Which is Better to Say? “Passed Away” or “Died”
While “passed away” is a euphemism for death, it is also a literal description of what many believe happens to our souls after we die. Because of this, the term “passed away” may feel comforting to most Americans.

However, because it is a euphemism that many people say, regardless of religious beliefs, you probably won’t go wrong by saying “passed away” or other similar comforting terms. You can watch the other family members if you wonder what they prefer to hear.

However, if someone does not believe in an afterlife, it’s unlikely they will think you mean it as a religious term and feel offended. “Passed away” and “pass away” are common terms that people use regardless of their belief systems.

Yes. Yes, they are afraid of the truth, but I'll allow latitude because it's often a harsh, painful truth.

Religion has done an exemplary job at coloring it all rosy with "they're in a better place" or "someday you'll be reunited in heaven," but there must be a thought nugget of reality deep down in the most pious believer that at one point whispers, "That's it. They're gone forever." Then, of course, they stomp all over that thought and chant the "live forever" mantra.

I think the biggest tragedy to that way of thinking is how it takes away people's ability to share their grief honestly, and discuss the harsh realities of having someone ripped from their life, when all they get is vacuous platitudes in return. I think the euphemisms often contribute to that by stopping people from having true emotional connection.

does either/any similar phrase have any secret meaning? maybe it's just the way their family has always talked...not everything is major, helllooooooooo

Yes

At least you know that "passed away" means that somebody died
We in France often say , when someone died: "X a disparu" = "X has disappeared", like a man who leaves the house to get some cigarettes, but never returns (but is still alive!).

When it comes to death we seem to use all kinds of euphemistic expressions as in he shuffled his mortal coil, he snuffed it, he passed away, gone to the sleep eternal, etc etc. We also use euphemisms to disguise some atrocity and make it more palatable. Perhaps the fear of death is rooted in a false notion of self, that is, somewhere in the back our minds we may sense that whatever the notion of self is it will dissolve in death.
