Since I mentioned the first phase of the moon yesterday, here is the word for the second phase. anrÅ«na refers to the first sliver after a new moon. It is also the word used for anything that has come back into view after being obscured.
There are six phases of the moon in all. The third one covers the first quarter to a waxing crescent moon. The word for that is anmÄ“Î»a, which also means “young“.
