ॐ • (om) m (Urdu spelling اوم‎)

1. om; aum

Etymology disputed.

• A. Parpola proposes borrowing from Dravidian, ultimately from Proto-Dravidian *ām (“let it be so, it is so, yes”), a contraction of *ākum, cognate with Tamil ஆம் (ām, “yes”).
• M. Blumfield proposes derivation from Proto-Indo-European *au (introductory particle) via *ō >* ōṃ > ōm, cognate with Ancient Greek αὖ (aû).
• The Upaniṣads propose multiple Sanskrit etymologies, including: from आम् (ām, “yes”); from एवम् (evam, “that, thus, yes”); and from आप् (āp, “to attain”) or अव् (av, “to urge”).
