Cognates are words from different languages that look similar and mean the same thing. These words are usually derived from and share the same etymological origin, which is an advantage if you're looking forward to learning a new language. For example, several words in other languages such as French and Spanish have similar appearances and meanings in English, with a few even having the same spelling.
