Alohomora (Spell that opens locks) - Derived from the
Hawaiian "Aloha" meaning "goodbye," and the
Latin word "mora," meaning "obstacle."
Avada Kedavra (Killing Curse) -
Aramaic phrase that means "I will destroy as I
speak."
Expelliarmus (Disarming Spell) -
Latin combination of "expellere" meaning "to
expel" and "arma" meaning "weapon or upper
arm."
Horcrux - "Horcrux"
when broken down in many languages means "outside the
cross." This is consistent with the very unholy nature of
creating one, and why it is stricken from the pages in a lot of
textbooks. "Crucis" means "pain or torture,"
and "hor" is a shortened form of the noun
"horreum," which means "storehouse." Thus,
"tormenting storehouse." A Horcrux is effectively a
"storehouse" for the part of the soul that an individual
destroys when killing someone. "Hor" can also remind
readers of the words "horrible" and "horrid."
The English meaning for "crux" is "the critical
feature or essence," like the crux of an argument. Similar to
the Latin translation, it then becomes understood as "essence
storehouse." Many consider the soul to be the essence of an
individual. A "crux" is also defined as a "difficult
puzzle," so Horcruxes can then be seen as "horrible"
or "tormenting puzzles." In Egyptian mythology, Horus was
the son of the god Osiris, who became the God of the Dead. Crux is
also Latin for "cross." If you combine these two words,
you get the "cross of Horus," also known as the
"ankh" (a cross with a loop at the top). The ankh was the
symbol of life. Thus, a Horcrux would ensure life.
