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.
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.
