Morphology
frication = fricate (opaque) = fric + ation
Although the form looks like a regular nominalization, the phonetics sense is a specialized technical extension and is not straightforwardly predictable from the base verb.
Etymology
Frication comes from the Latin fricare, 'to rub', and is like the word friction, so a helpful image is air 'rubbing' through a small gap in the mouth. So frication in speech means the noisy sound made when air rubs past parts of the mouth, as in the 's' of 'snake'.
