ode

The English ending -ode / -ody hides two unrelated Greek words. hodos meant 'way, path, road' and survives in electrode ('the path of electric current') and episode/episodic. ōidē meant 'song' and gives ode (a lyric poem), parody ('beside-song') and melodic ('tune-song'). They look the same in English but come from different roots — a true homonym collision.
