OK, here’s mine:
When you have a word that ends with a Heh and there is a patach under the Heh, the *PATACH IS PRONOUNCED FIRST* (just like a ches).
The word right in Ezras Avosainu (????????????? ) is not U-Mag-Bi-Ha. It’s U-Mag-Bi-AH (with a mapik heh).
Many ba’alei tefillah make the same mistake in Hallel with the Shem HaShem.
