Knowledge of English structure is more important than ability to spell words. The structure of English may be easily represented in sign language. It is easier to sign all parts of a sentence than sign some parts and fingerspell others. Any specific sign must mean one and only one thing. English should be signed as it is spoken, including idioms.
Plurality is indicated by number or by reduplication of a sign.
Space assignment and directionality are used instead of pronominal reference. Adjectives generally follow nouns. Progressive tense is indicated with reduplication of verbs.
