I discovered phonetic components a few months ago, and I’m always happy when I find a decent predictor. For example, after seeing 零 and remembering 令 from a few levels back I looked into 令 as a phonetic component predictor. Turns out that (based on my search on jisho.org) 令 is a pretty good indicator that a reading will be レイ.
I found one article about phonetic components, but does anyone have additional resources? Really I’d just like a place I could go to verify the usefulness of a phonetic component without having to look it up manually on jisho.org every time.
