anusaṁvicar

  In Sanskrit, "anusaṁvicar" refers to the anusvāra (अंस्वार), a nasal sound that represents a pure nasal articulation without specific oral closure, often transliterated as “ṃ” in Roman script.

Definition and Pronunciation

The anusvāra (अंस्वार) is a voiced, purely nasal sound produced by allowing air to pass through the nasal cavity while keeping the oral cavity largely closed

. Unlike regular nasal sounds like ‘na’, ‘ma’, or ‘ṇa’, which involve distinct oral articulations, the anusvāra does not require the tongue or lips to make contact; only the nasal passage resonates

. It is commonly written in Devanagari with a dot above the letter, e.g., अं.

The sound is approximated in English by the 'n' in words like 'saint', although in Sanskrit it is more of a purely nasal tone without the oral release

. In practice, the anusvāra may change its pronunciation due to sandhi rules, adapting to the closest nasal sound corresponding to the following consonant

Usage and Variants

1. Terminal usage: At the end of a word, the anusvāra can occur as a pure nasal (shuddhānusvāra), which may extend the preceding vowel in Vedic chanting

   . For example, in the Rigvedic text, “mahā indro” employs the as a pure anusvāra.
2. Sandhi adaptation: Before consonants (except for ś, ṣ, s, h), the anusvāra often becomes the corresponding nasal for the following consonant, e.g.,
   • संगः → सङ्गः (saṃgaḥ → saṅgaḥ)
   • संन्यासः → सन्न्यासः (saṃnyāsaḥ → sannyāsaḥ)

3. Substitution by म् (m): In classical Sanskrit grammar, words ending with anusvāra may, under specific conditions, optionally end with म् (m) especially when the next word begins with a vowel or the word ends a sentence

   . For example:
   • बालं (bālaṃ) → बालम् (bālam)
   • विद्यालयं (vidyālayam) → विद्यालयम् (vidyālayam)
