Yoruba Numbers 1 to 100: Counting System, Words & Pronunciation

The traditional Yoruba numbering system is one of the most sophisticated mathematical frameworks in African linguistics. Built on a vigesimal (base-20) foundation, it combines elegant addition and subtraction logic. Here is your complete guide to counting from 1 to 100, including how to count money and objects in everyday life.

Understanding the Base-20 (Vigesimal) Logic

Unlike English which counts in base 10 (decimal), traditional Yoruba arithmetic is centered around 20 (Ogún). Notice how numbers 11 to 14 use addition ("lé" = added to 10), while numbers 15 to 19 use subtraction ("dín" = subtracted from 20):

11 = 1 added to 10 → Oókànlá (Oókan lé ẹ̀wá)
14 = 4 added to 10 → Ẹ́rìnlá (Ẹ̀rin lé ẹ̀wá)
15 = 5 subtracted from 20 → Ẹ́ẹ̀dógún (Àrún dín ogún)
16 = 4 subtracted from 20 → Ẹ́rìndínlógún (Ẹ̀rin dín ní ogún)

Frequently Asked Questions About Yoruba Numbers

How do you count from 1 to 10 in Yoruba?
1: Ení (or Oókan), 2: Èjì (or Méjì), 3: Ẹ̀ta (or Mẹ́ta), 4: Ẹ̀rin (or Mẹ́rin), 5: Àrún (or Mẹ́rùn), 6: Ẹ̀fà (or Mẹ́fà), 7: Èje (or Méje), 8: Ẹ̀jọ (or Mẹ́jọ), 9: Ẹ̀sán (or Mẹ́sàn-án), 10: Ẹ̀wá (or Mẹ́wàá).
Why is the Yoruba numbering system based on 20 (vigesimal)?
Historically, Yoruba counting uses 20 (Ogún) as its mathematical base, reflecting all ten fingers and ten toes. Higher numbers are constructed by addition ('lé' meaning added to) and subtraction ('dín' meaning deducted from).
How do you say '100' in Yoruba?
100 in Yoruba is 'Ọgọ́rùn-ún' (meaning 5 twenties, 20 x 5 = 100).
What is the difference between counting objects and counting abstract numbers?
When counting abstractly in a list, you use 'Ení, Èjì, Ẹ̀ta...'. When specifying quantities of items (e.g. 2 books, 3 cars), you prefix with 'M-' (e.g. 'Méjì', 'Mẹ́ta', 'Mẹ́rin').
