Please excuse a short rant.
Guys, you have to learn radicals if you want to learn to read Chinese characters. You have to.
I bring this up because over and over again, I run into claims of a “secret” to or a “new method” for learning Chinese: radicals. Yes, it’s a bit of information you might not know when you first take an interest in Chinese, so it’s definitely worth stating explicitly to any new learner. But it’s not a “revolutionary way” to learn Chinese. It’s one of the fundamental building blocks of the Chinese written language. In fact, the Chinese themselves coud not possibly commit to memory the huge quantity of characters that literate adults know if the system did not somehow build on itself (through semantic elements and phonetic elements).
So it’s not “this great way to learn Chinese”; it’s the only way to really learn Chinese characters, unless you’re going to stop at a few dozen. Just as one does not typically learn to read English by skipping the alphabet, or begin studies in classical music by skipping musical notation, one does not tackle reading Chinese without learning about radicals.
(The latest place I ran into this “secret” was a TED talk called ShaoLan: Learn to read Chinese … with ease!)
Could we use new ways of learning Chinese characters? Absolutely. But radicals, or variations of Heisig’s method are not new. Learning thousands of characters is not effortless however you slice it. But it’s totally worth it!
So yes, learn radicals. Not because they’re some new idea, but because if you’re planning to learn Chinese in all its orthographic splendor, they’re one form of ancient Chinese wisdom that you simply can’t afford to ignore.
