Adacia

(ah-day-shah) a made-up (i think) combination of acacia (which is also quite nice) and dacey. dacey is a male name from what i know, but i like it as a girl's name much more than as a boy's (too similar to "daisy" perhaps). so adacia would be the formal version, and dacey the day-to-day informal version (i think it's great to have that kind of variety in a name).
