What does Zara mean?
In Arabic use Zara is most credibly a form of Zahra (root z-h-r), meaning 'flower/blossom' or 'radiant'. The name is genuinely cross-cultural and the origin is disputed: it also appears independently in Hebrew (sometimes linked, with weak support, to Sarah or to a root meaning 'to shine') and in Slavic and Spanish/Italian naming traditions, so the meaning depends on the family's background.
What does Jana mean?
As an Arabic name Jana (جنى, jana) means 'harvest' or 'the fruits one gathers', from the root j-n-y, and is associated by sound with janna ('garden, paradise'). Disambiguation: Jana is also a Slavic and Central-European feminine form of John/Jane, which is a wholly separate origin.
