buenas
/ˈbwenas/ · A1 · intj
hello, good morning, good afternoon, good evening (greeting used irrespective of the time)
👋 Short for buenas tardes/noches: just the good, time of day dropped
Buenas is the feminine plural of bueno (good), clipped from buenas tardes and buenas noches. Dropping the noun leaves a greeting that works at any hour, like saying just morning in English. Sounds like BWEH-nahs.
