Important Note:
* False cognates: Some words look similar but have different meanings. For example, "actual" in English means "real" but "actuel" in French means "current." Always check the context to be sure.
* Pronunciation: Even though the spelling is similar, pronunciation can be different. For example, "art" in English is pronounced with a short "a" sound, but "art" in French is pronounced with a long "a" sound.
Remember that these are just a few examples, and there are many more cognates in both languages. Learning to identify cognates can help you expand your vocabulary in both French and English.
