> the word whose usage is considered so offensive that it has caused the decline of its unfortunate near-homophone ‘niggardly’ That's not exactly a unique phenomenon. For example, it's how "rabbit" replaced "coney".
Which is funny because coney used to be pronounced more like cunny and was deliberately pronounced coney to get away from the vulgar associations.
That's still the only pronunciation I know. Rhymes with, and orthographically identical to, "money". (And "honey".)
