* Spanish: Both French and Spanish descend from Vulgar Latin, the everyday language spoken by Romans throughout their empire. This means they share a common ancestor and many cognates (words with similar origins and meanings).
* Italian: Similar to Spanish, Italian also developed from Vulgar Latin. The Romance languages (including French, Spanish, Italian, Portuguese, Romanian, and Catalan) all have their roots in this common ancestor.
* Portuguese: Portuguese is another Romance language, sharing the same Latin origin as French. Like the others, it exhibits similarities in vocabulary, grammar, and pronunciation, though distinct developments have occurred over time.
