@MikeMason-- I love some French words, they really do sound very pleasant to the ear. For example, I loved the name of that movie "Ratatoille." It's so harmonious and sweet.
There are also some words in English that I think are euphonious. Like "moonlight," "epiphany," "serenity" and "symphony." I love how these words sound and when several words like these are used in a phrase, it turns the whole thing into an euphony.
