Sounds simple, and it is a beautiful language, but till you get to letters like ches /chof, tes / tof, vais / vov straight, it can drive teacher and student to a standstill.
Not to mention, when the choilem over the vov is an oiy, (99% of the time) and when is a voi (like Mitzvois). Or my all time fav, when a pasach ches is chah (99% of the time) and when it ach (like Noiach)
Been there, so I know. Once you’ve got it, its poetry. Till you get it, its a tough ride.
