If by now you understand a *bit* of Arabic and want to continue studying Arabic *in* Arabic, get comfortable with Hans Wehr and progress through these playlists, I haven't found a better and more consistent progression path on youtube. The teacher is Ahmad Hashim. These are classroom recordings with great A/V quality. He teaches non-Arabs and his methodology is tailored for that. He does a great job of clarifying new words. But the best thing he does is teach you *how* to think about Arabic grammar and sarf, he doesn't just unload qawa`id.
