Potentially, all roots can be cast into all of the foci. Due to the semantics of the root, however, not many do in practice. Roots can differ in meaning when cast into different foci. The difference can be a slight nuance to almost opposite in meaning. For example, if the root dalus "clean" is cast in the Patient focus, the resulting meaning is "to clean (something)". But, if cast in the Directional focus, the resulting meaning is "to clean (something) off", the focused noun phrase becomes the area affected instead of the object affected.
