You're probably used to describing your language level as a learner, for example as A1 (beginner) or C1 (advanced).

Progressing from beginner to intermediate and then to advanced can take significantly longer than some might expect, with the 'intermediate' stage lasting many years, up to a decade even. (and that's okay!)

With vocab learning, I have observed different stages too: there's the Growth Stage (acquiring new words and expressions, actively doing a lot of the activities you learn about in Your Solid Vocab Memory) and also the Consolidation Stage (solidifying your language foundations without necessarily focusing on acquiring new vocabulary).

When you're in the consolidation stage, important vocabulary will naturally reoccur in language interaction. In other words: "If it is important, it will come back". And if you're not sure whether a word is important...you'll find out the next time it comes back!

In a consolidation phase, focus on natural language interactions, such as speaking and listening practice, especially with native speakers, so you can learn in the context that is right for your goals.

You'll naturally switch between these stages over the course of your language life.
