English has many words that end in “ty,” like liberty, beauty, and certainty, and they almost all come from French. The French versions end in “té” instead, so liberty becomes la liberté, beauty becomes la beauté, and certainty becomes la certitude. The pattern is simple for most of them: you just drop the “y” from the English word and add an accented “é.” But some words change their spelling a little more than that, and a few common ones have different endings altogether. Here are the most common ones with an example of how to use each.

Summary

Most English words ending in “ty” become French words ending in “té,” and the meaning stays the same. These words are always feminine, so they take “la” or “l'” as their article. A number of common ones change their spelling more, like certainty becoming la certitude, but the pattern still helps you recognize them. Learning this simple rule helps you guess many French words from English without needing a dictionary.
