Etymology
the word 'sooty' is a straightforward english formation from the native germanic root 'soot'. the old english noun 'sōt' has cognates across germanic languages, all referring to the black particulate matter from combustion. the adjective-forming suffix '-y', also of old english origin, is productively attached to nouns to indicate possession or abundance of a quality. therefore, 'sooty' literally means "full of or characterized by soot," a direct and logical descriptor for anything darkened by this substance. its semantic journey is transparent, maintaining a close link between the physical substance and the resulting state or colour.
