Are 汚い and いやらしい the same?


Is one exclusively for actual dirty while one is for just the feeling of
dirtiness, e.g. talking to a lewd pervert?




汚い is the most straightforward translation of "dirty". It's used both
literally (e.g., 汚い文字, 汚い服, 汚いトイレ) and figuratively (e.g., 汚い言葉, 汚い犯罪, 汚い組織).
It rarely has a sexual connotation. 汚い本 usually refers to a book covered with
mud, for example.

When いやらしい modifies a tangible object, it means "lewd". いやらしい本/映画 usually
refers to porn books/movies. But it's more commonly used to describe someone's
indecent, disgusting, sarcastic or filthy behavior. いやらしい言葉 may or may not
have sexual connotations depending on the context.
