Etymology
the word 'friction' entered english in the mid-16th century via french from the latin 'friction-', the stem of 'frictio', which means 'rubbing'. this latin noun is derived from the verb 'fricare', meaning 'to rub'. the core concept of rubbing, and the resistance and heat it generates, provides a direct and logical metaphorical extension. the physical sense of resistance between surfaces naturally evolved to describe interpersonal conflict or tension, mirroring the figurative sense of things or people 'rubbing each other the wrong way'.
Analysis
the word is a simplex form derived as a whole from latin.
