Counting in Proto-Indo-European
Proto-Indo-European (PIE) is the theorized common ancestor of the Indo-European language family, spoken between 3.500 and 2.500 BC. By linguistic reconstruction, linguists have reconstructed a language for which no direct record exists. The reconstructed numerals presented on this page are taken from the Late Indo-European stage, when the distinction with its parent, the Proto-Indo Hittite (PIE) has been done.
Due to lack of data, we can only count accurately up to 1,000 in Proto-Indo-European. Please contact me if you can help me counting up from that limit.

Proto-Indo-European numbering rules
Now that you’ve had a gist of the most useful numbers, let’s move to the writing rules for the tens, the compound numbers, and why not the hundreds, the thousands and beyond (if possible).
- Digits from one to nine are rendered by specific words: oinos/oinā/oinom (m/f/n) , dwōu/dwāi/dwoi (m/f/n) , trejes/trja or trī/trísores (m/f/n) , qétwores , penqe , seks , septḿ , oktṓu , and newṇ . It seems that weks, six, could have been the ‘original’ PIH (Proto-Indo Hittite) form, to which an s- from septḿ was added; it would have lost the w- later.
- The tens are formed starting with the multiplier unit, directly followed by the suffix -dkṃta (group of ten), with no space, except for twenty: dekṃ , dwid kṃtī or wid kṃtī , trídkṃta , qetwŕdkṃta , penqédkṃta , swé ksdkṃta or sé ksdkṃta, septḿdkṃta , oktṓdkṃta , and néwṇdkṃta .
- Compound numbers from eleven to nineteen are formed starting with the unit, then the word for ten (dekṃ), separated with a space: sémdekṃ or oinos dekṃ , dwōu dekṃ , trejes dekṃ , qétwores dekṃ , penqe dekṃ , sweks dekṃ , septḿ dekṃ , oktṓ dekṃ , and newṇ dekṃ .
- Compound numbers above twenty are formed starting with the unit, then the ten separated with a space (e.g.: qétwores tridkṃta , oktṓu penqédkṃta ).
- Hundreds are formed starting with the multiplier digit root, directly followed by the plural form of the word for hundred (singular: dkṃtóm or kṃtóm, plural: kṃtos), with no space, except for one hundred: dkṃtóm , dwikṃtos , trikṃtos , qatwṛkṃtos , penqekṃtos , sekskṃtos , septṃkṃtos , oktōkṃtos , and newṇkṃtos .
- Compound hundreds start with the unit, then the ten and the hundred, separated with spaces (e.g.: penqe dekṃ dkṃtóm , oinos qetwŕdkṃta septṃkṃtos ).
- The word for thousand is sṃgheslom [1,000].
Write a number in full in Proto-Indo-European
Let’s move now to the practice of the numbering rules in Proto-Indo-European. Will you guess how to write a number in full? Enter a number and try to write it down in your head, or maybe on a piece of paper, before displaying the result.
