Use this tool to add tone marks to pinyin or to convert tone number (e.g. hao3) to tone marks.

Although you can use the red buttons to add tone marks, we highly recommend you use the number method (e.g. hao3) for speed and placement of the accent above the correct vowel. [Hint: Type "v" for "ü"]

I mentioned last week in my post Written Chinese: Where do I start? that when I first came to China, the idea of a radical was just as foreign as I was and being able to use them to read had never even crossed my mind.

I remember the class when my Chinese teacher said we were going to do some writing. She gave my friend and I one of those books with the grids they give to school children and I just thought: ‘I have no idea what I’m doing!’


You can call it defeatist, or a bad attitude, but I honestly thought that it was just too complicated for little old me. Even as we started I felt like I couldn’t even hold the pen properly to make a stroke. Actually by the end of the class I quite enjoyed myself, but it wasn’t until after a few weeks that she began to teach us about radicals. That was when I got really excited about learning to read and write Chinese. The fact that characters had a meaning, that they weren’t just lots of lines that sometimes made pretty pictures was amazing! The penny dropped (from a great height), a light bulb went on after a long powercut and I realised that maybe I actually ’got’ it and that even I had a chance to learn to read and write Chinese.

We have written several posts focused on radicals and their meanings and it seems as though a lot of you really understand the value of radicals. However, there are lots of newcomers to Written Chinese and so it seems fitting to now explain the reason why learning radicals is important in order to further your Chinese.

So let’s start by having a look at the following characters:

休, 你, 们, 作

 Now let’s have a look at the left side of all four characters. You can probably see that what they all have in common is this: (rén). This is a radical meaning ‘person’. The ‘person’ radical is also the stand alone character 人, the radical is just turned slightly on its side.

So what does that mean?

It means that these 4 characters (xiū), (nǐ), (men) and (zuò) are all related in some way to people.

Person radical

I guess what we need to remember is that this written language has existed for thousands of years and has gone through many transitions, not all of them particularly sympathetic to the meaning of a character. The result is that sometimes, the meaning of a radical in relation to a character is a little hard to understand, because it is based on a traditional meaning. However, in this case the four characters have a direct connection to the (rén) radical.

(xiū) is a pictographic character so it can literally be taken apart. We have 亻meaning person and (mù) meaning tree (you can check out our blog post on 木字旁: The Tree Radical later for more information on that.). So what would a person be doing stood next to a tree? Having a rest of course! After hours of working in the fields, he sits down in the shade of the tree and relaxes.

The meaning of (xiū) is to have a rest.

The meaning of the next three is less obvious, but because of the radical you can tell that they must have something to do with people.

 (nǐ) – You

 – (men) Plural marker for pronouns

– (zuò) To do

A radical usually indicates the meaning or pronunciation of a character.

Let’s do a little test and see if you know or can guess the radical and meaning of these characters. When you think you know, move your mouse over the image to show the meaning.

How did you do?

Radicals are not only important to help us understand the meaning of the character, but it also helps when using a dictionary. Now, I know most of us are using online dictionaries and Chinese dictionary apps such as WCC Dictionary, but there are still people using those things made of paper (shock!). Basically, in order to use a 汉语词典 (hàn yǔ cí diǎn) or Chinese Dictionary (made of paper) you need to have a good knowledge of radicals to find a characters.
梅膺祚 (Méi Yīng Zuò) developed the radical-and-stroke-sorting principle during the Ming Dynasty, which was published first within the 字汇 (zì huì) or ‘Lexicon’. This means that characters are listed by radical and then ordered by the number of strokes needed to write them. Actually, our own WCC Chinese Dictionary Mobile App also uses a similar function!

Check out More Chinese Radials

Here are some basic instructions for using a Chinese Dictionary:

  1. First you need to know which radical the character was indexed under. You can probably guess by using the element on the left or on top of the character.
  2. Find the section of the dictionary related to that radical.
  3. Count the strokes in the remainder of the character (not including the radical strokes)
  4. Find the pages that include the radical that also have the number of additional strokes.
  5. Find the character you’re looking for, or repeat steps 1-3.

Let me give you an example.

I want to find this character 晚 in the dictionary. So following my steps, first I need to know which radical to look for…

晚,氜 radical

1. I looked at the left of the character, and found (rì), the sun radical.

Finding 日2. Now I know that this character has the radical 日, I can find the pages in the dictionary.

FoundGot it!

Found 晚

3+4. Now, I have to find the section with the 日 radical and +7 strokes. I should check out page 634 for the character ‘晚’.

晚 definition

5. There it is at the bottom of the page!

晚 page cuIf you weren’t sure, (wǎn) means evening or night.

So, grab yourself a dictionary and get searching!

    Thanks for posting. I have a question about one statement you made: “A radical usually indicates the meaning or pronunciation of a character.” Can you provide an example of a radical indicating pronunciation?

    • Hollie Sowden

      Hi Steven,

      There are two ways to look at this:

      1. As an element of a character in our dictionaries (online and app) we refer to all the elements of a character as a radical. So in this case, the side of the character that gives the pronunciation of the character. For example, If we look at ‘钟’, the right hand side 中 (zhōng) ‘radical’ teaches us to pronounce the 钟 character with ‘zhōng’.

      2. If you only assume that radicals are on the left or bottom of a character, there are still examples (but for more rare characters) of the left or bottom radical also suggesting pronunciation. For example ‘虖’ (hū) meaning ‘to shout’, has the tiger radical, 虎 (hǔ) to suggest pronunciation. I hope that kind of explains my point a little more. Thanks, Hollie

      • Steven Skyles

        Thanks for your reply. I suppose if you expand the definition of “radical” to include any part of the character, then I can see it. I’ve always defined “radical” as the classifier part of the character only, and that most Chinese characters consist of a radical (classifier) and a separate sound element.

        In your second example, while it’s true that 虖 contains the tiger radical 虍 (which as a standalone character is pronounced hū ), it also contains the sound element 乎 (also pronounced hū). I would argue that 虖 gets its pronunciation from the 乎 part of the character, and not from the radical.

        • Nora Joy Wilson

          Good point, Steven. I wanted to mention that the term “classifier” is also used when learning Chinese synonymous with “measure word”, or those little article words which pair with nouns like 个 (ge4), 只 (zhi1), etc. for those of you newbies out there.

          It’s true that on our site, we use the term “radical” more generally to mean the pieces of a character which may suggest sound or meaning. Perhaps it’s not the best possible way to describe the character components, but it’s a way that we try to make learning less complicated and to avoid confusion in terminology.

          Thanks for the valuable feedback 🙂 Keep the comments coming!
