Consider how you've learned every other practical skill as an adult, and notice how little of it resembles a language course.
Driving
You didn't study the mechanics of a clutch before touching one. You got in and did it badly, with somebody sensible beside you, repeatedly, until it stopped requiring attention.
Nobody assessed your theoretical understanding of the biting point. The test was whether you could do it without thinking — which is the only meaningful test of a skill.
Cooking
You didn't complete a syllabus. You made the same handful of things repeatedly until they became automatic, then extended outward from there.
You probably still couldn't explain why one method works and another doesn't. It hasn't affected the dinner.
An Instrument, a Sport, a Craft
The same pattern everywhere. Small amount of material, heavy repetition, performance from the first session, understanding arriving afterwards as a description of what you were already doing.
Nobody learns guitar by studying theory for two years and then picking one up. Everybody knows that's the wrong order, and nobody finds it controversial.
Language Is the Exception, and Only by Accident
Languages get taught as an academic subject because they're taught in schools, and schools teach academic subjects. The format came from the institution, not from the skill.
So the one thing you're most likely to actually want to do — speak — gets learned in the format designed for things you only need to know.
Applying the Normal Approach
Treat it like any other skill and the changes follow automatically.
A small amount of material at a time. Perform from the first session, badly. Repeat well past the point where you feel you know it, because knowing and doing are different. Let the theory arrive later, as a description.
None of that is a novel method. It's simply what you'd do for anything else, applied to something usually handled differently for historical reasons.
About Outputly
Outputly treats a language the way you'd treat any other skill — a few things at a time, produced out loud from the first session, repeated until they stop needing you.
