the compositionality dimension
above we saw that brow raise can be used alone or in combination with other semiotic units such as words, i.e., it is compositional. in sign languages brow raise can be used together with manual signs (which are equivalent to spoken words). in spoken languages brow raise can also be used together with words however within sign languages there seem to be more restrictions on how brow raise is combined with signs/words. the first major difference is that in some sign languages brow raise is obligatory in yes-no questions (dachkovsky and sandler, 2009), while in spoken languages it is not. the second difference is that facial expressions that take part in composite sign structures seem to be more strictly timed to the onset and offset of signs/words compared to spoken languages (veinberg and wilbur, 1990). it would seem that there is an increase in the combinatorial options for facial expressions when shifting from use of the face with spoken language to use of the face as part of signing similar to that proposed for gesticulation and sign language in mcneill (1992).
