Read it.

How it works

Layered from N5 to N1

Start with basic particles and build toward complex subordinate clauses - each concept scaffolds the next without gaps.

Every word color-coded

Particles stand out visually in every example. You'll stop reading sentences and start seeing their structure at a glance.

Drills that build sentences

Rather than multiple-choice, you assemble sentences yourself - particle by particle - until the logic is automatic.
