What does Raya mean?
As an Arabic name Raya has two attested sources: rayya (ريا) 'aroma, fragrance, perfume', and raya (راية) 'flag, banner, ensign'; the intended sense varies by family, so it is best treated as disputed. Disambiguation: Raya also means 'celebration' in Malay (Hari Raya) and appears in Hebrew ('friend') and Slavic use - unrelated origins.
What does Mariam mean?
Mariam (مريم) is a widely used transliteration of the same Arabic name as Maryam, the form of biblical Mary/Miriam honoured in Islam as the mother of the prophet 'Isa. It carries the identical etymology (ultimately the Hebrew Miryam, meaning disputed); the spelling simply reflects regional pronunciation and romanisation preferences.
