On’yomi and kun’yomi?

On’yomi are readings that came from Chinese, written here in katakana. Kun’yomi are native Japanese readings, written in hiragana. Which one is used depends on the word: kanji in compounds often take an on’yomi, and a kanji standing alone often takes a kun’yomi.

What is a radical?

Dictionaries file every kanji under one of 214 radicals, a component used for looking it up. A shared radical often hints at a shared theme, but not always, and it says nothing certain about a character’s history. A radical can change shape inside a kanji, as 水 becomes 氵.
