lol come on, please tell me that you're kidding :)
If you want to learn Latin, take a grammar and start! It's completely impossible to read a few spells in Latin and expect that it's a good base to start writing them on your own.
I learned it for 5 years, and believe me, it's a really long way to get to the stadium in which you will be able to write anything in that language!!!
Magic doesn't know the limits of language, so your spells will be of the same power in Which-ever language :)
As Unlucky Raven said , not that hard really , English people dont have Noun Declenision so that may appear hard, that and tenses , Consecutio temporurum and as Raven said irregular verbs.
Verbs and nouns also decline and conjugate dependind on gender which is not case in english so that might be another "put off"
As for latin as magiokal language it is indeed the most powerful one, earler when Practitioners and spirits where much closer and tight working , Practitioners used latin as universal , melodic and chanty langauge because they were suggested to do so by spirits themself , and experience had shown indounbtly that spirits are rather fond of it even nowadays.
Also writing words of power in Latin makes Your spells unvversal in cosmopolitic sense , as long as one that will uses them takes time to understand what the words mean.
Being a dead langauge there is no danger of evolving so the spells preserved in Latin remain uncorrupted indefinitely ,where as in any "living" langauage word's get new meanings every day depending on context in which used, causing misstranslations and possible confusion.
Making and effort to speak Latin , which spirits as i have said before are fond of , show them Your respect and makes them more willing to assist one :)
Learning Latin is the key to unlocking several modern languages, including French, Spanish and Italian. not to mention much of the English language. Good luck!
