For detailed instructions, see the Component builder how to guide.
To find any kanji, first try to identify the components it is made up of. Once you have identified any component, search for it in any of three ways:
  1. Draw it in the drawing area
  2. Type the name in the text area
  3. Look for it in the list
Example: look up 漢
  • Notice that 漢 is made of several components: 氵 艹 口 夫
  • Draw any of these components (one at a time) in the drawing area, and select it when you see it
  • Alternatively, look for a component in the list. 氵 艹 口 each have three strokes; 夫 has four strokes
  • If you know the meanings of the components, type any of them in the text area: water (氵), grass (艹), mouth (口) or husband (夫)
  • Keep adding components until you can see your kanji in the list of matches that appears near the top.
Kanshudo Component Builder Drawing Help
The Kanshudo Component Builder can recognize any of the 416 components listed in the chart below the drawing area. Tips:
  • Draw a component in the center of the area, as large as you can
  • Try to draw the component as it appears in the kanji you're looking up
  • Don't worry about stroke order or number of strokes
  • Don't draw more than one component at a time

Grammar detail: 窪む(くぼむ)and 凹む(へこむ, くぼむ)

窪む(くぼむ)and 凹む(へこむ, くぼむ)

My current mastery of this grammar point:
LOG IN to view grammar mastery data
In Japanese there are two key words meaning 'become dented', 'cave in' etc: へこむ and くぼむ.
へこむ is the more versatile, because it can refer to either physical or psychological depression. くぼむ on the other hand only refers to physical depression.
へこむ is written in kanji as
む using 凹, the standard kanji for 'concavity'. くぼむ can be written with either 窪 as
む or 凹 as
む. In other words, without furigana,
む is indistinguishable from
む. Because of this ambiguity, Japanese prefer to write くぼむ using 窪 (even though it is actually not a Jōyō kanji), or increasingly just with kana, reserving 凹 for へこむ.
