I suggest REPEATING.
Although this method of learning is out of fashion in the west, I deeply reommend it! Why? Well, have you ever seen ethiopian children tutored by a priest, repeating the Ha-Hu, or fidel (alphabet)? It is amazing!
I went to the children's class of the EOC in my city and enjoyed very much learning with them!
In my opinion in the west the method of constant repeating is wrongly disrespected. They say it stops people from thinking and just makes them a vessel to put infos into them. I disagree and tell you why:
Repeating is good for our brains. It might not be the method for EVERY subject, but especially for languages it is great! Cause how does a baby learn it's first language? Repeating. It heard his mother say thousands of times 'mama' before it starts to articulate 'mamamamama...'.
Repeated words go deep deep deep into a man's subconscious. Like a foundation where you'll build your house upon. Mek sure it is solid, not rubble! Languages works same way as Mantras. Not to be taken lightly. Fix good words inna you. Repeat words and sentences. Full sentences can be remembered very well if they are repeated again and again. By that method I learned full psalms in Amharic. Later I remembered them and that helps with the grammar as well. Repeating is a method of touching people deeply. Strong VIBRATION that works the best!
