Speak with the ease and color of a native speaker: idiomatic fluency.

This is the vocabulary that makes you sound like you grew up speaking English — everyday idioms and phrases native speakers use instinctively, often without even noticing they're figurative. Mastering these completes your journey from rules to true fluency.

Why this matters This lesson connects directly to your progress: it covers everyday native idioms; nuanced native expressions; idiomatic fluency markers. Mastering this content lets you move forward confidently, and reinforces patterns you'll use again later. Take time to review every example before moving to the assessment — repetition is what actually locks knowledge in long-term.
