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 Aryan mean?
From Sanskrit arya (आर्य), 'noble, honourable, worthy'. The original sense is one of nobility and virtue; it is unrelated to later misappropriations of the term.
