Sobriquet

I came across a lovely word.
Mellifluous. French?

Sobriquet

It means a fanciful name or nickname. It can be spelled sobriquet or soubriquet. It is from French, so be sure to say, so-bri-kay!

So my sobriquet is Philolog!

more soothing sounds:
somni FA cient--hypnotic!
somniferous--soporific
soporific--tending to cause sleep or dull awareness, also hypnotic according to Webster's New Collegiate Dictionary.
somnolent--drowsy or sleepy, but no mention of hypnosis.

You can also say soporiferous instead of soporific! They are synonyms. However, soporiferous sounds more soothing to me.
