Uses of "le"

The Chinese particle 了 has been traditionally divided into two broad categories: aspectual particle 了 (AKA 了1) and modal particle 了 (AKA 了2). However, for a word with as many varied grammatical uses, such broad classifications don't seem particularly helpful to learners. This article offers an alternative way to understand 了: by listing out specific uses and patterns without regard for traditional classifications, starting with the ones learners will want to learn right away, and moving into more and more complicated uses.
