This lesson explains the difference between DUAL and DUEL: illustrations, definitions, examples, tips, practice story, final quiz, and answers. Dual and duel are examples of homophones, meaning that they are said the same way, but have different definitions. There are lots of homophones in English and it can be hard to keep them all in order when you are learning, but it is very important that you don't mix these two up. One of them means that there are two of something, while the other means a fight! So you definitely wouldn't want to use one when you mean to use the other. Once you learn the definitions, you should have no problem getting it right. Let's take a look at some examples in order to help you understand each word better.
