Master English number multiples with this simple guide. Learn single, double, triple, quadruple, and more to boost your English fluency.

Number multiples are a useful part of English vocabulary, especially when describing repeated actions, amounts, or patterns. In this lesson, you will learn the words used for multiples of numbers, from one to ten.

We start with single for one, and then move to double for two, and triple for three. These are very common in everyday English, especially when talking about amounts, sports scores, or even phone numbers. For example, people often say “double zero” or “triple five” when giving a number.

Beyond that, you can use quadruple for four, quintuple for five, and sextuple for six. These words are less common but appear in academic, scientific, and technical contexts.

Next, there’s septuple for seven, octuple for eight, nonuple for nine, and decuple for ten. While you may not hear these every day, knowing them helps you understand advanced English vocabulary.

By practicing these multiples, you’ll strengthen your ability to describe numbers clearly and confidently. Watch the video, repeat each word, and try making your own example sentences using these multiples.
