What does Sana mean?
Sana (سناء, sana') derives from the root s-n-w/s-n-y and means 'radiance, brilliance, splendour'. It should be distinguished from the unrelated Arabic word sana ('year') and from Sana'a, the Yemeni capital.
What does Zaina mean?
Feminine form tied to Arabic زين (zayn) 'beauty, adornment', from the root z-y-n. Shares the same root as Zayn and the name Zaynab.
