Counting Of Numbers - Ordinal & Cardinal
Counting in Igbo Language

The Igbo Numerals

The scope of Igbo numerals (cardinal and ordinal) is limited. This is because in the original Ibo society, the Ibos did not need to count a vast number of things ranging up to millions as in modern times.

After a number of nnụs (i.e. 400's), they merely regard other things as uncountable or agụta-ọnụ, narị anỡ, kwuru nnụ.

The land marks in counting are 1 to 10 ( otu, abụa, atọ, anọ, ise, isii, asaa, asatọ, iteghete, iri); ọgụ or oru (20); narị anọ (400 i.e. 20 x 20).

The Igbo Numbers (Onu Ogugu)

There are two different counting systems in Igbo language that differ slightly from one another.

The older and most popular system is based on the number 20 (twenty)(Ohu). While the recent created decimal system is based on the number 10 (ten)(Iri).

The new version, a slight modification of the old system, was created in an attempt to make Igbo counting less cumbersome by bring it in line with recent developments in the academic world.

The first nineteen numbers are the same in both systems. After that, the basis of counting changes from multiples of twenty in the "old system" to multiples of ten in the new system.

Both of them however are still in use and will continue to be in use for years to come.

Here is what the new system look like in Anambra and Imo states Igbo. Note that since 1970s, only the Imo state Igbo are taught at school, before that Anambra Igbo.
