Angel
The name angel is used for heavenly messenger spirits, because Greek angelos means “messenger”. The spooks have perhaps promoted that name, and sometimes seem to misuse angels as hoax markers, because it puns with engelao for “mockery”. A similar pun may exist in Hebrew, where m-lˀk means “messenger” & “angel”, which puns with m-lˁg for “mockery”.
One example where angel-like wings were apparently misused as a hoax marker was the fake death of Gabby Petito, plus the owl, Halloween, 9/11, monarch butterfly, a moon and probably others. Even the names seem puns: Gabby Petito is similar to “[rumour for] petty-gabbing” and “begabbing the little [people]”. The fake murderer’s name Brian Laundrie is similar to “brainwashing”.
It goes without saying that there’s nothing wrong with the belief in or the depiction of angels. Humans believed in protective spirits long before the spooks screwed everything up.
