Declension tables, for me, provide an easy and accessible insight into the repetition of grammar patterns and help me while in doubt.
I have attended no formal courses of Latin, all I know I've learned by myself, with the aid of this wonderful tool the Internet is. Thankfully, my knowledge in Spanish and some simple 'introductory' lessons were all I needed to start delving into this beautiful language.
I didn't start alone, however. A friend of mine engaged in the study of Latin too, though he has so far dropped it. Though at the beginning we gave a try to conversation in Latin, which was most useful.
My own method includes the memorization of declension and conjugation tables, the study of vocabulary and practice (through translation efforts - thank God for this Forum) as well as conversational practices by myself. If speaking to yourself was ever thought as crazy, imagine speaking to yourself in Latin.
I also share Cato's woe. Sadly, Latin is merely learned to read the Classics, and not for conversational purposes. How I wish my friend could retake his learning of Latin, or to meet more people interested in this language.
Sadly, there are not Latin Circles or anything like that in Panama, to my own chagrin.
Thankfully, this Forum does have a Latin chat section, and though I still haven't posted there yet (as Iynx once prompted me to do so) I will soon, when I believe I have mastered my grammar sufficiently enough to have a steady flow of give-and-take.
I have no standard with which to measure my progress, but my own subjective evaluation of myself. I might be going at this the wrong way, but thanks to all of you, I have a continuous flow of corrections and evaluations.
