You are not learning more slowly. You are reaching for the same few hundred words every day, and they keep working.
The intermediate plateau doesn't feel like stalling while you're on it. It feels like fluency. You can handle your day, your work, your usual opinions. Conversations go fine. What's actually happened is that you've assembled a working kit of a few hundred words and a dozen structures that covers almost everything you normally need, and you now reach for that kit every time.
Every time you use it, it gets faster and smoother. That's real improvement, and it's the wrong kind. Speed on the forms you already own doesn't add new ones, and the kit is self-reinforcing: because it always works, you never hit the wall that would force you to build something else.
Ask someone on the plateau to describe their weekend and they'll do it well. Ask them to describe a process they've never explained, or an event they didn't witness, or a hypothetical they disagree with, and the fluency thins out immediately. The vocabulary was never the whole problem. The kit simply doesn't contain a way to say those things, and normal life never asks.
Free writing has the same weakness. Given a blank page and no constraint, you'll write what you can write. Nobody voluntarily walks into the part of a language where they sound clumsy, so unconstrained practice tends to circle the same few hundred words for months and feel productive while doing it.
The way out is to make the easy answer unavailable. Not more practice, different practice, where the task itself blocks the kit:
Write about something outside your routine. Not your day, but a process, a piece of news, a decision someone else made, a thing that hasn't happened yet. Unfamiliar content drags unfamiliar structures in with it, because you can't describe a hypothetical with the grammar of a diary.
Ban your favourite structure for a week. Everyone has one, usually a simple frame that can be bent to cover far too much. Take it away and you'll be forced into the constructions it has been substituting for.
Change the register. Write the same content as a complaint, then as an instruction, then as a polite request. Register changes force different verb forms and different politeness machinery, which is where a lot of intermediate learners are thinnest.
Say it a second way. Write the sentence, then write it again without the words you used the first time. The second version is where the new form appears.
All of these produce worse writing than you're capable of, and that's the sign they're working. Reaching for a form you don't own means making mistakes in it, which means a period where your output looks less competent than it did on the plateau. If your practice always looks good, it's almost certainly recycling.
This is also where correction stops being optional. Reaching for new forms generates errors by design, and errors that nobody catches become the next layer of the kit. Producing new structures badly, repeatedly, unchecked, is how a learner ends up fluent in an accent of their own invention. The point of the constraint is to generate mistakes worth fixing, which only pays off if something is fixing them and keeping track of which ones keep coming back.
Every daily prompt is really a constraint, chosen so the task can't be answered with yesterday's sentence. That's most of what a prompt is for. Not inspiration, but a rule that makes your kit insufficient for one sentence a day.
Mening sends you one prompt a day in the language you\'re learning, corrects what you write, and keeps count of which mistake keeps coming back.
