Read Chinese you cannot type. Scan it, draw it, speak it or
paste it, and get the characters, Mandarin (Pinyin),
Cantonese (Yale) and English — with audio for both.
Type English to get Chinese back.
Then ask why. Our advanced Chinese AI answers questions
about the language itself — what a character is
built from, when to use one word over another, why a
sentence is phrased the way it is. It answers about
Chinese and nothing else, which is what makes it good
at it.

Quick start
Type into the text box, or fill it by scanning an image, drawing characters or speaking.
When drawing, tap a suggested character to add it to the box. Tap Clear canvas when you are ready for the next one.
Tap Translate & Pronounce. Chinese gives you English; English gives you Chinese, with Pinyin and Yale either way, and a speaker on each to hear it.
Copy any result, tap play to hear it, or open the full page for any character.
Whatever is in the text box is loaded into the ask box underneath as you go, so asking our advanced Chinese AI about it is a press — before you translate it, instead of translating it, or after. Change the question to whatever you want to know: a character, a grammar point, the difference between two words. Press one of the examples to see what it does.

Radical纟
FrequencyExtremely common as a component: one of the most productive radicals in Chinese, though never used as a standalone word.
纟 is not a word you can say on its own — it is the simplified form of the 'silk' radical, written on the left side of characters to do with thread, cloth, rope, colour and binding. Its traditional counterpart is 糹 (six strokes), the side-form of the standalone character 糸. You will meet it constantly, in 红/紅, 线/線, 纸/紙, 给/給, 经/經, 绿/綠 and hundreds more.
Mandarinsī · ㄙ
Cantonesesi1 · sī
The parent character 糸 is read mì (jyutping mik6) when treated as an independent character, but as a radical everyone calls it sī / si1 after 丝 'silk'.
radical (bound component)the 'silk' radical in its simplified left-side form; marks characters relating to thread, silk, cloth, rope, tying and colours
noun (of the parent character 糸)fine silk thread (archaic, only in classical or technical use)

How it is built
pictograph
Radical 纟. silk, thread.
纟meaning a cursive-derived contraction of 糹, itself the side form of 糸
Origin
The parent graph 糸 appears on oracle bones and bronzes as a picture of a twisted skein or hank of silk threads, with loops above and loose ends splayed at the bottom. In the regular script this became 糹 when squeezed onto the left of a character. The three-stroke 纟 of simplified Chinese comes from the long-established cursive (草书) way of writing 糹, where the loops collapse into two small turns over a single rising stroke; it was standardised in the 1950s simplification and applied wholesale to every character with this radical.
Remembering it
Two little loops and a flick at the bottom: a tangle of thread with the loose end hanging out. Whenever you see it, expect thread, cloth or colour — 线 line, 纸 paper, 绿 green, 织 to weave.
纟is a component, not a character you can use in a sentence; dictionaries file it under radical 120. Its spoken name in Mandarin is 绞丝旁 (jiǎosīpáng), in Cantonese 絞絲邊 (gaau2 si1 bin1). Traditional-character readers write 糹 with three dots at the foot, so 红/紅, 给/給, 经/經 differ only in this radical — learning the swap converts hundreds of characters at once. When 糸 sits at the bottom of a character (紧/緊, 素, 累) it keeps its full six-stroke shape even in simplified Chinese, except where the whole character was simplified.
Context
The density of silk-radical characters — for colours, for 经 'warp threads' hence 'classic text', for 结 'to tie' hence 'to conclude' — is a fossil of how central sericulture was to early Chinese life; abstract vocabulary about order and connection was borrowed straight from the loom.
