I've begun my first Latin lessons this week. I changed my schedule around so that I could take Latin 101 (an online class -- public schooling). Although the class is teaching me classical Latin and not ecclesiastical I am still learning a lot. I do well at knowing and deciphering the Latin stem of a word, and am now learning how to put words together and how to conjugate my verbs and declensions.
It's fairly easy stuff actually!
This class is already helping me to understand English grammar better along with the little bit of Spanish and Italian I know. The hardest part is knowing what is different in classical Latin compared to ecclesiastical.
What this class has really helped me with is learning the definitions and sentence structures of Latin words or phrases that I apply weekly (sometimes daily) at Mass or in prayer. I knew before what most words meant, but now I can see their true definitions and purpose in certain contexts along with picking more and more words up as I go along because I am becoming more familiar with them.
Which also allows me to see all of the terrible and (in some cases) liturgically wrong translations that the English Mass uses, the ones I was (sadly) brought up on.
