Developed in the US in 1966 by a deaf teacher named David Anthony, Seeing Essential English (SEE1) was intended to teach proper grammatical construction by using signs borrowed from ASL but it implements English word order, and other grammatical markers, such as conjugation. In SEE1, all compound words are formed as separate signs - instead of using the ASL sign for butterfly, SEE1 places the signs for butter and fly in sequential order. Many signs from ASL are initialized in SEE1 – the ASL sign for have is signed with the B handshape in SEE1. Grammatical markers also have signs of their own, including the -ing ending and articles such as the, which are not typically included in ASL. SEE1 is occasionally referred to as Morphemic Sign System (MSS), and it has also been adapted in Poland into seeing essential Polish. Note:
