Learning objectives
- Lesson goals: Learn the three core uses of で: place of action, means/tool, and reason.
- Form and connection: [Noun] で
- Nuance in real use: で is like a ninja with three identities — the same sound marks location, tool, and cause. One of the joys of learning Japanese is discovering how a single particle shape-shifts across contexts.
