The Truth Behind Wizarding Spells

        As I mentioned in the previous post, wizarding spells are, 99% of the time, derived from Latin words. Here are some well-known spells and their English meanings. Most spells are from Latin though there are a few exceptions. We'll start off with a personal favorite:

Expecto Patronum-I expect a guardian 
Lumos-Latin for light 
Nox-Latin for night 
Imperius-Modification of impero, meaning I order
Crucio-Modification of cruciare, meaning crucify/torture
Avada Kedavra-From Aramaic abracadabra, meaning let the thing be destroyed, the thing being life
Expelliarmus-Expel means to throw out, and armus is Latin for arm
Sectumsempra-Sectum means to cut, and sempra is close to semper, meaning always 
Stupefy-Similar to Latin stupeo, 'to be stunned'
Accio-Modification of accerso, Latin for to summon
Aguamenti-Aqua means water, and augmen means growth
Alohomora-West African word meaning 'friendly to thieves'
Impedimenta-Latin for burden, though the spell in fact slows to victim
Wingardium Leviosa- Wing invokes flight, ard means steep, and levi means levitate (ard and levi are from Latin)
Protego-Latin for 'I cover, defend'
Obliviate-Derived from Medieval Latin obliviscor, which means 'I forget'
Riddikulus-Close to English ridiculous and Latin ridiculum in both meaning and pronunciation, means laughable
Reparo-Latin for 'I restore'
Levicorpus-Levi means levitate in Latin, and corpus means body in Latin
Incendio-From Latin incendo, meaning 'I set fire to'
Priori Incantatem-Priori means prior, and incantatem comes from a Latin ford meaning to sing or recite (similar to present-day English incantation)
Confundo-Modification of confundere, Latin for confuse/mix
Homenum Revelio-Derived from hominis (man) and revelare (to reveal)
