[Binary relationship: x connected_to y if and only if there exists some z such that z connects x and y in a ternary connected_to(x,y,z) relationship., a is connected to b if and only if a and b are discrete structure, and there exists some connecting structure c, such that c connects a and b]
[c connects a if and only if there exist some b such that a and b are similar parts of the same system, and c connects b, specifically, c connects a with b. When one structure connects two others it unites some aspect of the function or role they play within the system., Binary relationship: z connects x if and only if there exists some y such that z connects x and y in a ternary connected_to(x,y,z) relationship.]
[[copied from inverse property 'occurs in'] b occurs_in c =def b is a process and c is a material entity or immaterial entity& there exists a spatiotemporal region r and b occupies_spatiotemporal_region r.& forall(t) if b exists_at t then c exists_at t & there exist spatial regions s and s’ where & b spatially_projects_onto s at t& c is occupies_spatial_region s’ at t& s is a proper_continuant_part_of s’ at t]
[p contributes to morphology of w if and only if a change in the morphology of p entails a change in the morphology of w. Examples: every skull contributes to morphology of the head which it is a part of. Counter-example: nuclei do not generally contribute to the morphology of the cell they are part of, as they are buffered by cytoplasm.]
