Mute English is a phenomenon, especially common in the People's Republic of China, where people can read and understand English as a second language but cannot speak it well. The phrase is a calque of the Chinese phrase "哑巴英语" (yǎbā yīngyǔ in pinyin). The phenomenon is sometimes referred to as Dumb English. Though any language can have its form of mute speakers (e.g. Mute Polish), the phenomenon of 'Mute English' in China is a massive, acknowledged problem, one which the school systems and students are attempting to address. A related concept is the less-common Deaf English.
