Visarga

In Sanskrit phonology, Visarga (IPA: [ʋisɐrɡɐ(hɐ)]) is the name of the voiceless glottal fricative, written in Devanagari as 'ः' [h]. It was also called, equivalently, visarjanīya by earlier grammarians. The word visarga (Sanskrit: विसर्ग) literally means "sending forth, discharge". In Bengali script, visarga is written as ঃ and is called bisarga (বিসর্গ). It generally represents a post-vocalic voiceless glottal fricative-like release, though in modern Bengali it is mostly realized as a slight aspiration after the vowel. Bengali visarga can also occur medially, as in দুঃখ, দুঃস্বপ্ন, and often corresponds etymologically to Sanskrit visarga.

Visarga

Visarga is an allophone of /r/ and /s/ in pausa (at the end of an utterance). Since /-s/ is a common inflectional suffix (of nominative singular, second person singular, etc.), visarga appears frequently in Sanskrit texts. In the traditional order of Sanskrit sounds, visarga and anusvāra appear between vowels and stop consonants.

The precise pronunciation of visarga in Vedic texts may vary between Śākhās. Some pronounce a slight echo of the preceding vowel after the aspiration: aḥ will be pronounced [ɐhᵄ], and iḥ will be pronounced [ihⁱ]. Visarga is not to be confused with colon.

Types

The visarga is commonly found in writing, resembling the punctuation mark of colon or as two tiny circles one above the other. This form is retained by most Indic scripts.

According to Sanskrit phonologists, the visarga has two optional allophones, namely जिह्वामूलीय (jihvāmūlīya or the guttural visarga) and उपध्मानीय (upadhmānīya or the labial visarga). The former may be pronounced before ⟨क⟩, ⟨ख⟩, and the latter before ⟨प⟩, and ⟨फ⟩, as in तव पितामहः कः (tava pitāmahaḥ kaḥ?, 'who is your grandfather?'), पक्षिणः खे उड्डयन्ते (pakṣiṇaḥ khe uḍḍayante, 'birds fly in the sky'), भोः पाहि (bhoḥ pāhi, 'sir, save me'), and तपःफलम् (tapaḥphalam, 'result of penances'). They were written with various symbols, e.g. X-like symbol vs sideways 3-like symbol above flipped sideways one, or both as two crescent-shaped semi-circles one above the other, facing the top and bottom respectively. Distinct signs for jihavamulīya and upadhmanīya exists in Kannada, Tibetan, Sharada, Brahmi and Lantsa scripts.

Other Brahmic scripts

Bengali

In the Bengali script, the visarga is written as ঃ and is known as bisarga (বিসর্গ). In Bengali it represents a weak post-vocalic release rather than a clearly articulated /h/ sound. Although it originates from Sanskrit final r- and s-sounds, modern Bengali preserves it primarily as an orthographic element, with its phonetic value varying according to position and environment.

Phonetic behaviour

When occurring medially within a word, the bisarga no longer produces a distinct aspiration; instead it tends to reinforce or lengthen the following consonant. Examples include দুঃস্বপ্ন or নিঃশ্বাস, where the bisarga historically reflects Sanskrit ः, but in Bengali the release is replaced by consonant strengthening or an increased sibilant effect.

When occurring finally at the end of a word, the bisarga marks an etymological aspiration inherited from Sanskrit, but in contemporary Bengali it is realised only as a very faint breath or is silent. Forms such as তঃ or যঃ illustrate this weakened contrast. Overall, Bengali pronunciation treats the visarga not as an independent consonant but as a modifier whose audible effect ranges from minimal to null.

Visarga Sandhi

In sandhi environments, the bisarga undergoes several regular transformations that depend on the nature of the following sound. These changes reflect its Sanskritic origins and are largely systematic in Bengali spelling, even when their phonetic effect is weak.

Before vowels, the bisarga commonly yields র or produces an ও-glide, preserving the historical continuity of r-final forms (e.g. পুনরধিকার). Before sibilants and coronal or palatal stops, it assimilates to the following consonant as the appropriate sibilant—শ, ষ, or স—a process that accounts for forms such as নিঃচয় → নিশ্চয়.

When followed by voiced consonants or semivowels, r-jāt bisarga typically appears as র, while s-jāt bisarga may produce an ও-transition; thus অন্তঃগত surfaces as অন্তর্গত. If the following consonant is র, the bisarga disappears entirely and the preceding vowel lengthens, as seen in নীরস. After the vowels ই or উ and before velar or labial stops, the bisarga may appear as ষ, producing forms such as নিষ্কাম.

Some compounds retain the written bisarga without any phonological modification, as in মনঃক্ষুণ্ণ. In other cases, the bisarga may be lost without affecting adjacent sounds, as in অতএব from অতঃ + এব. As a whole, visarga sandhi in Bengali reflects historical Sanskritic patterns that are preserved orthographically even though their phonetic realisation is limited in modern speech.

Burmese

In the Burmese script, the visarga (variously called ရှေ့ကပေါက် shay ga pauk, ဝစ္စနစ်လုံးပေါက် wizza nalone pauk, or ရှေ့ဆီး shay zi and represented with two dots to the right of the letter as း), when joined to a letter, creates the high tone.

The Visarga mark used by Motoori.

Motoori Norinaga invented a mark for visarga which he used in a book about Indian orthography.

Javanese

In the Javanese script, the visarga, known as the wignyan (ꦮꦶꦒ꧀ꦚꦤ꧀), is represented by two curls to the right of a syllable as ꦃ: the first curl is short and circular, and the second curl is long. It adds a /-h/ after a vowel.

Kannada

In the Kannada script, the visarga (which is called visarga) is represented with two small circles to the right of a letter ಃ. It adds an aḥ sound to the end of the letter.

This script also has separate symbols for ardhavisarga absent in most other scripts, jihvamuliya, ೱ, and upadhmaniya, ೲ.

Khmer

In the Khmer script, the visarga (known as the reăhmŭkh (រះមុខ; "shining face")) indicates an aspirated /ʰ/ sound added after a syllable. It is represented with two small circles at the right of a letter as ះ, and it should not be confused with the similar-looking yŭkôlpĭntŭ (យុគလពិន្ទុ; "pair of dots"), which indicates a short vowel followed by a glottal stop like their equivalent visarga marks in the Thai and Lao scripts.

Lao

In the Lao script, the visarga is represented with two small curled circles to the right of a letter as ◌ະ. As in the neighboring related Thai script, it indicates a glottal stop after the vowel.

Malayalam

In the Malayalam script, the visarga is represented with two small circles to the right of a letter as ഃ. It indicates a /h/ after a letter. Visarga is considered as a vowel in Malayalam, where its independent form is written as അഃ. Unlike other languages, visarga need not necessarily occur at the end of a word. Examples include ദുഃഖം, മനഃപ്രയാസം, പുനഃസൃഷ്ടി.

Odia

In the Odia script, the Bisarga is represented with a vertical infinity sign to the right of a letter as ଃ. It indicates the post-vocalic voiceless glottal fricative aḥ [h] sound after the letter, Unlike other languages, the bisarga can appear in middle of words, such as ନିଃଶ୍ବାସ, ନିଃସ୍ବ, ନିଃସନ୍ଦେହ, ନିଃଶେଷ etc. All words with Bisarga aren't borrowed from Sanskrit.

Sinhala

In the Sinhala script, visarga is represented with two small circle to the right of a letter as ඃ.

Tamil

In the Tamil script, similar to visarga (which is called āyuta eḻuttu (ஆயுத எழுத்து), āytam (ஆய்தம்), muppāl puḷḷi, taṉinilai, aḵkēṉam, ak), transliterated as ḵ, is represented with three small circles to the right of a letter as ஃ. Its used to transcribe an archaic /h/ sound inherited from the proto Dravidian *H that has either become silent or geminates the next letter in unlearnt speech, or pronounced as /k/ or /h/ in careful speech. Like Sanskrit, it cannot add on to any letter and add aspiration to them. It should be always placed between a single short vowel and a hard consonant (க், ச், ட், த், ப், ற்) for example அஃது (aḵtu), எஃகு (eḵku). The āytam in modern Tamil is used to transcribe foreign phones like ஃப் (ஃp) for [f], ஃஜ (ஃj) for [z], ஃஸ (ஃs) for [z, ʒ] and ஃக (ஃk) for [x], similar to a nuqta.

Telugu

In the Telugu script, there are two visargas. One is represented with two small circles to the right of a letter ః. It brings an "ah" sound to the end of the letter.

Thai

In the Thai script, the visarga (known as the visanchani (วิสรรชนีย์) or nom nang thangkhu (นมนางทั้งคู่)) is represented with two small curled circles to the right of a letter as ◌ะ. It represents a glottal stop that follows the affected vowel.
