Signed Polish (język migany) or System Językowo-Migowy (SJM), is a manually coded form of Polish that uses the signs of Polish Sign Language ("Polski Język Migowy", PJM). It is commonly used for simultaneous "translation" of Polish into sign. A second system, Signing Exact Polish, is mostly used in education.
