Every number has an English name written in words. For example, 1 in words is "one," and 9 in words is "nine." When we study the history of numbers, we see that "zero" was discovered by an Indian mathematician, Arya Bhatta, which changed the course of numbers and made it possible to continue counting after 9. Hence, 10 were formed. This is followed by 11, 12, 13,... Here we will learn how to name numbers from 11 to 20. They are the set of numbers that, when discussed in the sense of human age, are the precious years of someone's life.
Suppose we went to a shop to buy 11 candies, and we had to say the number 11 aloud to the shopkeeper.
So, how should we say it?
Intellectual people from ancient times have given names to numbers; below, we will discuss them one by one, in brief, to get a holistic view of numbers in words, from 11 to 20.
Eleven (11): The word "eleven" means that after counting to ten, "one is left." It occurs after 10 and before 12.
Twelve (12): The words eleven and twelve are recognised to have the same origin. Hence, "twelve" means "two is left" after finishing counting to 10. It comes after 11 and before 13. The collection of twelve objects is called a dozen.
Thirteen (13): with the suffix "teen," it is the first number in numerical order, coming after 12 and before 14.
Fourteen (14): Next to thirteen, there is fourteen, with "four" as a prefix and "teen" as a suffix.
Fifteen (15): It is an odd number that comes after 14 and before 16. "Fif" as a prefix derived from "fifth," with the suffix "teen.
Sixteen (16): After fifteen, there is sixteen. with the suffix "six," originating from the number 6, and the suffix "teen."
Seventeen (17): before 18 and after 16, seventeen comes. It is the only prime that is the sum of four consecutive prime numbers. With the prefix "seven" and the suffix "teen."
Eighteen (18): "eigh" originates from eighth, and "teen" as the suffix. It comes after 17 and before 19.
Nineteen (19): The end of the "teen" numerical range is nineteen. With the prefix "nine" and the suffix "teen."
Twenty (20): with the suffix "ty" and prefix "twen," it means twice the number ten. It comes after 19 and before 21. A group of 20 objects is also known as a "score."
Below is the list of numbers with words in table form:
Numbers | Words | Numbers | Words |
11 | eleven | 16 | sixteen |
12 | twelve | 17 | seventeen |
13 | thirteen | 18 | eighteen |
14 | fourteen | 19 | nineteen |
15 | fifteen | 20 | twenty |
Numbers from 11 to 20 are natural numbers.
The prime numbers are 11, 13, 17, and 19.
Composite numbers are 12, 14, 15, 16, 18, and 20.
12, 14, 16, 18, and 20 are even numbers, whereas 11, 13, 15, 17, and 19 are odd numbers.
You can find out the detailed other number in words article list below:-
Eleven, twelve, and twenty are the numbers that do not have the suffix "teen." Instead, they have their unique names.
11 is the number that comes after ten. According to its etymology, the word for 11 originated with a reference to 10. "Eleven" means "one after ten."
Twelve is a number called a "score" when we measure a quantity, just like how twelve is also referred to as a "dozen."
Fifteen is a number that is composite but not even, as it is not divisible by 2.
Nineteen is the end numerical number with the suffix "teen", with its prefix being derived from "nine."
