What does Leila mean?
Variant spelling of Layla, from Arabic 'layl' meaning 'night'. The 'Leila' form was popularized in English via 19th-century Western literature.
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.
