This concept is used heavily in ASL (American sign language). Simple signs can be grouped to make other concepts. There are conjugations or tenses -- explicit number and time are their own signs -- and articles and prepositions are usually dispensed with, much like headlines. Example "teacher" is TEACH PERSON. Plural would be TEACH PEOPLE. Student is LEARN PERSON, etc. There are the equivalent of modifiers indicated by motion, facial expression, etc. This sounds wordy but in practice the bit rate is about the same as spoken because some signs stand in for multiple things, plus the omissions and modifiers as above are meaning multipliers.
