Belasan

Belasan is an Indonesian word used to denote a quantity or age range that is "teen" or in the range of thirteen to nineteen. It is derived from the root word "belas" which signifies "ten" and is commonly used to form numbers in this specific range. For example, thirteen is expressed as "tiga belas," fourteen as "empat belas," and so on, up to nineteen, which is "sembilan belas."

The term "belasan" is not just limited to numbers. It can also be used to refer to the age group. When someone says they are in their "belasan," it means they are between thirteen and nineteen years old, encompassing their teenage years. This usage is common in everyday conversation and in contexts where a more general age bracket is being discussed rather than a precise age.

In a broader sense, "belasan" can sometimes be used informally to refer to a number or quantity that is "a dozen and a bit more," or simply a number in the teens. However, its primary and most precise meaning relates to the numbers thirteen through nineteen and the corresponding age group. The structure of forming these numbers, by adding a single digit to "belas," is consistent across the entire range, making it a straightforward concept within the Indonesian numeral system.
