Radical Notes are FREE (yippee!) and are intended to complement the essays. Each Radical Note focuses on a particular radical, examining its Japanese and English names, variations on its shape, its positions in a kanji, and characters that contain it. 

If the term "radical" is unclear to you, see the next-to-last section of the glossary, as well as Radical Terms.

In the index below, you'll notice that every radical has a number. This numbering system has nothing to do with the Henshall numbers for each kanji. For instance, 心 (heart) is radical 61 and is kanji number 147. The radical numbers correspond to the 214 historical radicals in the Kangxi Dictionary of China. Nelson, Halpern, and Denshi Jisho also use this radical numbering system.

Radical Notes have loose structures; you never know just where the discussions will go. In some cases, such as Radical Note 5, the text is quite brief, pointing you to an essay. That's because the end of that essay will be tantamount to a Radical Note. In many other instances, such as Radical Note 140, you'll find a sizable chunk of writing.

This library of Radical Notes will grow. For every Joy o' Kanji essay published, a corresponding Radical Note will appear below if it's not already there. For example, when the 鬱 (1963: depression; gloom; melancholy) essay posts, so will Radical Note 192 on the "fragrant herbs" radical, 鬯.
