What does Aarav mean?
From Sanskrit arava (आरव), literally 'a sound, roar, or shout'. Although hugely popular today and widely marketed as meaning 'peaceful' or 'calm', that gloss is a modern reinterpretation not supported by the root; the attested classical sense is 'noise/sound', sometimes softened to 'melody'.
What does Arjun mean?
From Sanskrit arjuna (अर्जुन), 'white, bright, silvery, clear'. Best known as the heroic third Pandava prince and Krishna's friend in the Mahabharata; the literal root sense is 'shining/white' rather than 'warrior'.
