Awesome Word (Or Phrase) of the Unspecified Random Time Period

Effervescent: adjective: Effervescent means sparkly, fizzy, or bubbly, and can be applied to either a liquid or a person. This seems to me one of those words that sounds like what it means, whats the term I'm thinking of... ah yes, a homophone*.  Effervescent is just a sparkly word. "Layla's effervescent personality lit up a room." mmm.... I really do like this word.

*No, wait, that's wrong. I can't believe I had that up for three weeks without noticing that. The word I was looking for was onomatopoeic. Effervescent is onomatopoeic, not a homophone. Grrr. Stupid confusing English language.
