All words are contexts, as contexts they can take static and dynamic roles.
A static role may be a noun and its modality, or as dynamic a verb and its modality.
For example red may both be a noun and a modality, or (although incorrect in english) it may be a verb and its modality.
It is this universal nature of the word as having so many functions that a context can be expressed dualistically.
For example:
"The reddest red redded rededly the redder red."
{((R)r) [[R --->]r] ((R)r)}
Thus all words are recursive contexts that exist in multiple states at the same time.
