Numbers and Counting in Kikuyu

🎯 Lesson Goal

Counting is one of the most practical things you can learn in any language. In this lesson you will learn how to count in Kikuyu, starting with the numbers 1 to 10 and then using those same building blocks to make bigger numbers. You will see that Kikuyu numbers follow clear patterns, so you do not need to memorize every number from 1 to 100 one by one. Learn a handful of key words and a few simple rules, and you can build the rest yourself.

This is a practical beginner lesson that teaches learners how to:

• Count from 1–10 in Kikuyu.
• Recognize numbers from 11–19.
• Count by tens.
• Form larger numbers such as 21, 35, and 48.
• Understand the basic pattern used to construct larger numbers.
• Say the months of the year in Kikuyu.

How the lesson is organized: first you learn the numbers 1 to 10, then the “teens” (11–19), then the tens (20 to 100). After that you learn how to join tens and ones to make numbers such as 21, 35 and 48, and you meet the words for hundreds, thousands and millions. Finally, you learn the names of the months, which you will need for dates. A pattern summary pulls it all together, and the lesson ends with practice questions and a short written exercise so you can check what you have learned.

🎯 Introduction

Numbers are used in almost every daily conversation. Whether you are chatting with a neighbour, buying vegetables at the market or catching a matatu, you will hear and use numbers all the time. Knowing how to count in Kikuyu will help you:

• Give your age. People often ask how old someone is, or how old their children are.
• Shop and understand prices. At the market or the shop, you will need to understand how much something costs and how many items you are buying.
• Talk about quantities. You can say how many people are in a family, how many children someone has, or how many goats, chickens or bags of maize there are.
• Tell prices and handle money. Knowing the numbers helps you bargain, count change and know what you are paying.
• Give dates and times. Numbers are needed to talk about the day of the month, the time of day or how many days until an event.

The good news is that Kikuyu numbers follow a clear pattern. There are only ten basic number words to learn (1 to 10). From these, you can build the numbers 11 to 19 by adding to ten. You can build the tens (20, 30, 40 and so on) with one repeating word, mĩrongo, which means “tens.” And you can join a ten to a single digit to make any number in between, such as 21 or 48.

A tip for learning: do not try to memorize everything at once. Start by saying the numbers 1 to 10 out loud until they feel natural. Then look for the pattern in each new group. Once you see how the pieces fit together, the bigger numbers become much easier. Try counting objects around you in Kikuyu, such as the steps on a staircase, the fingers on your hand or the items in your bag, so that the numbers become a habit and not just words on a page.

🔢 Numbers 1–10

Pronunciation note: Kikuyu has two special vowels. ĩ sounds like the “i” in “bit,” and ũ sounds like the “u” in “put.” The ng in words like mĩrongo and ngiri sounds like the “ng” in “finger.”

🔢 Numbers 11–19

To make the numbers 11 to 19, say ikũmi (ten), then na (and), then the number from 1 to 9. In simple English: “ten and one,” “ten and two,” and so on.

Break-down of 15: ikũmi (10) + na (and) + ithano (5) = 15.

The other numbers follow the same pattern: 13 = ikũmi na ithatũ, 14 = ikũmi na inya, 16 = ikũmi na ithathatũ, 17 = ikũmi na mũgwanja, 19 = ikũmi na kenda.

🔢 Tens: 20–100

The pattern: the word mĩrongo means “tens.” To say 30, 40, 50 and so on, say mĩrongo and then the number of tens: mĩrongo ĩtatũ is “tens three,” which is 30.

The number changes slightly after mĩrongo. When a number follows mĩrongo, some of the counting words take a slightly different form:

So 20 is mĩrongo ĩrĩ (not mĩrongo igĩrĩ), and 40 is mĩrongo ĩna (not mĩrongo inya).

100 has its own word: igana.

🔢 Numbers Above 20

To make a number such as 21 or 35, say the tens first, then na (and), then the number from 1 to 9. This is genuinely how Kikuyu builds these numbers.

Step by step, using 21 as an example: start with the tens (mĩrongo ĩrĩ, 20), add na (and), then finish with the ones (ĩmwe, 1).

🔢 Hundreds, Thousands & Larger Numbers

Notes: Numbers can also be said with “one,” for example igana rĩmwe (one hundred) and ngiri ĩmwe (one thousand). For 10,000 and 100,000, say ngiri (thousand) and then how many thousands: ngiri ikũmi is “thousand ten,” and ngiri igana is “thousand hundred.” Mirioni (million) is a borrowed word.

🔢 Months of the Year

When you talk about dates, you also need the months. In Kikuyu, the months are named by number. The word mweri means “month,” wa means “of,” and a number word tells you which month it is. For example, Mweri wa mbere means “the month of first,” which is January. In the month names, the numbers 2 to 8 take special forms: kerĩ (2), gatatũ (3), kana (4), gatano (5), gatandatũ (6), mũgwanja (7) and kanana (8). From September onward the months use the ordinary numbers 9 to 12: kenda, ikũmi, ikũmi na ũmwe and ikũmi na kerĩ.

🧩 Pattern Summary

1–10: Each number has its own word. Learn them one by one.

11–19: ikũmi (10) + na (and) + a number from 1 to 9.

Tens: mĩrongo (tens) + the number of tens. 20 is mĩrongo ĩrĩ. 100 is igana.

Numbers above 20: tens + na (and) + a number from 1 to 9. Example: mĩrongo ĩrĩ na ĩmwe (21).

Months: mweri wa (month of) + a number word. Months 2 to 8 use special forms (kerĩ, gatatũ, kana, gatano, gatandatũ, mũgwanja, kanana).

Hundreds/thousands: igana (100), ngiri (1,000). Say ngiri + the number for larger amounts. 1,000,000 is mirioni.
