Etymology

Origin of sonorous

1605–15; < Latin sonōrus noisy, sounding, equivalent to sonōr-, stem of sonor sound ( son ( āre ) to sound 1 + -or -or 1 ) + -us -ous

Explanation

Used to describe sound or speech that is full, rich, and deep, sonorous is a great word for snoring, for bass voices, and for low notes on the tuba. Skip the first "o" and you'll see snore inside this word, which should give you a clue as to its deeply resonant character. Another way to remember sonorous is that son sounds like "sound," and that's what this word is all about.
