By the way, "icositetrahedron" appears in some dictionaries.

The dual of the rhombicuboctahedron has been called either
a trapezoidal or tetragonal icositetrahedron, while the dual
of the snub cube is a pentagonal icositetrahedron.

I saw the word "tetrakaidecahedron" in a recent "press release"
from the Minneapolis Geometry Center, so you can see that people
DO occasionally use such words.
