Real words, not loose letters
Every lesson is built around one word you'd actually meet outside — a place, a food, a sign. You learn the letters by reading something real.
Why it works
Learning researchers call automatic word recognition orthographic mapping. Words become instant after you've sounded them out a handful of times — but only if the letter-sound link is real, not memorized as a shape. Anchoring every lesson to a meaningful word gives your brain that link from the start.
