Finding a kanji in a dictionary

Radicals are also how kanji are indexed in paper dictionaries. Every character is filed under exactly one classifying radical.

To look a kanji up, you first find its radical by number (1–214), then count the remaining strokes — the strokes added after the radical — and scan that small group.

This “radical + residual stroke count” method lets you find a character even when you have no idea how it is read.
