分解 · What it is made of

The parts of 哲

Almost every kanji is built from a small set of reusable parts. Learn the parts once and you stop memorising thousands of unrelated shapes.

Why it sounds the way it does. The part is the phonetic component — it carries the sound rather than the meaning. That is why 哲 is read てつ. Roughly two-thirds of all kanji work this way, which makes unfamiliar readings guessable once you spot the pattern.
