Tamil numerals

Tamil is written in a non-Latin script. Tamil text used in this article is transliterated into the Latin script according to the ISO 15919 standard.

The Tamil language has number words and dedicated symbols for them in the Tamil script.

Basic numbering in Tamil

Zero

Old Tamil possesses a special numerical character for zero (see Old Tamil numerals below), which is read as andru (literally, no/nothing); yet Modern Tamil renounces the use of its native character and uses the Indian symbol '0' for Shunya meaning nothingness in Indic thought. Modern Tamil words for zero include சுழியம் (suḻiyam) or பூஜ்ஜியம் (pūjjiyam).

First ten numbers (முதல் எண்கள்)

Modern Tamil script	Tamil numeral	Tamil word and transliteration
௦	0	சுழியம் (suḻiyam) Old Tamil: பாழ் (pāḻ)^[1]
௧	1	ஒன்று (oṉṟu)
௨	2	இரண்டு (iraṇḍu)
௩	3	மூன்று (mūṉṟu)
௪	4	நான்கு (nāṉku)
௫	5	ஐந்து (aindhu)
௬	6	ஆறு (āṟu)
௭	7	ஏழு (ēḻu)
௮	8	எட்டு (eṭṭu)
௯	9	ஒன்பது (oṉpathu)
௰	10	பத்து (paththu)

Transcribing other numbers

Reproductive and attributive prefixes

Tamil has a numeric prefix for each number from 1 to 9, which can be added to the words for the powers of ten (ten, hundred, thousand, etc.) to form multiples of them. For instance, the word for fifty, ஐம்பது (aimpatu) is a combination of ஐ (ai, the prefix for five) and பத்து (pattu, which is ten). The prefix for nine changes with respect to the succeeding base 10. தொ the unvoiced consonant of the succeeding base 10 forms the prefix for nine. For instance, 90 is தொ ண் (ண் being the unvoiced version of ணூ), hence, தொண்ணூறு).

Tamil script	Tamil prefix	Transliteration
௧	ஓர்	ōr
௨	ஈர்	īr
௩	மூ	mū
௪	நான்	nāṉ
௫	ஐ	ai
௬	ஆறு	āṟ(u)
௭	ஏழ்	ēḻ(u)
௮	எண்	eṇ

These are typically void in the Tamil language except for some Hindu references; for example, அட்ட இலட்சுமிகள் (the eight Lakshmis). Even in religious contexts, the Tamil language is usually more preferred for its more poetic nature and relatively low incidence of consonant clusters.

Specific characters

Unlike other modern Indian number systems, Tamil has distinct digits for 10, 100, and 1000. It also has distinct characters for other number-based aspects of day-to-day life.

ten	hundred	thousand
௰	௱	௲

௳	௴	௵	௶	௷	௸	௹	௺

Powers of ten (பதின்பெருக்கம்)

There are two numeral systems that can be used in the Tamil language: the Tamil system which is as follows^[2] ^{[clarification needed]}

The following are the traditional numbers of the Tamiḻakam region.^{[clarification needed]}

Partitive numerals (பகுத்தல்)

Fractions (பின்னம்)

Proposals to encode Tamil fractions and symbols to Unicode were submitted.^[3]^[4] As of version 12.0, Tamil characters used for fractional values in traditional accounting practices were added to the Unicode Standard.

Transcribing fractions (பின்னம் எழுத்தல்)

Any fraction can be transcribed by affixing -இல் (-il) after the denominator followed by the numerator. For instance, 1/41 can be said as நாற்பத்து ஒன்றில் ஒன்று (nāṟpattu oṉṟil oṉṟu).

The suffixing of the -இல் (-il) requires the last consonant of the number to be changed to its இ (i) form. For example, மூன்று இல் (mūṉṟu -il) becomes மூன்றில் (mūṉṟil); note the உ (u) has been omitted.

Common fractions (பொது பின்னங்கள்) have names already allocated to them, hence, these names are often used rather than the above method.

^ Aṇu was considered as the lowest fraction by ancient Tamils as size of smallest physical object (similar to an atom). Later, this term went to Sanskrit to refer directly to atoms.^{[citation needed]}

Decimals (பதின்மம்)

Decimal point is called புள்ளி (puḷḷi) in Tamil. For example, 1.1 would be read as ஒன்று புள்ளி ஒன்று (oṉṟu puḷḷi oṉṟu). In Sri Lankan Tamil, Thasam தசம்.

Percentage (விழுக்காடு)

Percentage is known as விழுக்காடு (viḻukkāḍu) in Tamil or சதவீதம் (śatavītam). These words are simply added after a number to form percentages. For instance, four percent is நான்கு சதவீதம் (nāṉku satavītam) or நான்கு விழுக்காடு (nāṉku viḻukkāḍu). Percentage symbol (%) is also recognised and used.

Ordinal numbers (வரிசை எண்கள்)

Ordinal numbers are formed by adding the suffix -ஆம் (ām) after the number, except for 'First'.

Ordinal	Tamil	Transliteration
First	முதல்	mudal
Second	இரண்டாம்	iraṇḍām
Third	மூன்றாம்	mūṉṟām
Fourth	நான்காம்	nāṉkām
101st	நூற்று ஒறாம்	nūṟṟu oṉṟām

Collective numerals (கூட்டெண்கள்)

English	Tamil	Transliteration
Single	ஒற்றை	oṟṟai
Pair	இரட்டை	iraṭṭai
Reproductives	௺ வினைச்சொல்	Numeric prefix noun*
Single (pillar), double (pillar)...	ஒருக்(கால்), இருக்(கால்)-	oruk(kāl), iruk(kāl)*
Distributives	௺ முறை	Numeric prefix muṟai
Once, twice...	ஒருமுறை, இருமுறை	orumuṟai, irumuṟai

As always, when blending two words into one, an unvoiced form of the consonant as the one that the second starts with, is placed in between to blend.

Influence on other dravidian languages

As the ancient classical language of the Dravidian languages, Tamil numerals influenced and shaped the numerals of the others in the family. The following table compares the main Dravidian languages.

1	oṉṟu	ondu	onnŭ	oñji	okaṭi	okkod	oṇṭa	asiṭ	*oru(1)

10	pattu	hattu	pattŭ	patt	padi	padī ³	dassē (II)	dah (II)	*pat(tu)

Also, Tamil through the Pallava script which itself through the Kawi script, Khmer script and other South-east Asian scripts has shaped the numeral grapheme of most South-east Asian languages.

History

Before the Government of India unveiled ₹ as the new rupee symbol, people in Tamil Nadu used the Tamil letter ௹ as the symbol. This symbol continues to be used occasionally as rupee symbol by Indian Tamils. It is also used by Tamils in Sri Lanka.

The symbol ௳ is also known as the Piḷḷaiyār Suḻi (lit. 'Curl of Piḷḷaiyār'), a symbol that most Tamil Hindus will start off any auspicious document with. It is written to invoke the god Piḷḷaiyār, known otherwise as Ganesha, who is the remover of obstacles.
