French Cognate Patterns: English Endings and False Friends
By Michael McGettrickUpdated 12 October 2026
A French cognate is a word French and English share, usually because English borrowed it from French. Three tricks decode most of them, and one list stops them misleading you.
| Trick | French | English |
|---|---|---|
| Swap the ending | | liberty |
| Read the gender | | the situation |
| Put the s back | | forest |
| False friend | | the bookshop (!) |

The six core swaps
Most shared words differ only in their ending, and six endings do most of the work.
| English | French | Example |
|---|---|---|
| -tion | -tion | |
| -ty | -té | |
| -ous | - | |
| -ly | - | |
| -ic | -ique | |
| -ary | - | |
.- The situation is serious..- It's dangerous..- It's simply necessary.
The first barely changes at all, but it sounds different: French -tion is said syon, with a nasal vowel, never shun.
Two of the rows hide a detail:
- - is . The feminine is -euse:
,(a dangerous road). - - is built on the adjective:
gives(slowly). The full rule is on French -ment adverbs.
More endings that swap cleanly
| English | French | Example |
|---|---|---|
| -ist | -iste | |
| -ism | -isme | tourisme |
| -ance, -ence | -ance, -ence | |
| -ive | -if, -ive | |
| -or, -our | -eur | |
| -ate (verb) | -er | |
.- My brother is an artist.?- What is the difference?.- She wants to take part.
The -iste nouns are one word for a man or a woman; only the article changes: , . The -if adjectives become -ive in the feminine, which hands you both English forms: , .
The gender comes free
Many cognate endings fix the noun's gender too, the part of French vocabulary that is hardest to guess.
| Ending | Gender | Example | Exceptions |
|---|---|---|---|
| -tion, -sion | | none to worry about | |
| -té, -ité | | , | |
| -ance, -ence | | | |
| -isme | tourisme | none | |
| - (nouns) | | none to worry about |
.- The question is difficult..- The government has changed.
So the ending gives you both the word and, nearly always, or . The rest of the gender patterns are on French noun gender.
The hidden s
One swap is not an ending at all. French lost an s before a consonant in hundreds of words, and modern spelling marks the gap with an accent. English borrowed many of them before the s went, so the English word still has it.
| French | The accent | English |
|---|---|---|
| é = | school |
| é = | state |
| é = | strange |
| ê = | forest |
| ô = | hospital |
| ê = | feast |
| î = is | isle |
.- The hospital is closed..- It's a strange story.
The rule of thumb: an é at the start of a word, or a circumflex in the middle, often marks a lost s. Put it back and see whether an English word appears. Not every accent works this way (, ), but enough do to decode words you have never seen.
Why English has two words
The Normans conquered England in 1066, and French ran the English court, law and administration for about three hundred years. English swallowed French vocabulary wholesale.
| Plain English | From French | French today |
|---|---|---|
| freedom | liberty | |
| ask | demand | |
| kingly | royal | |
The practical consequence: the more formal the English word, the more likely it is French. Stuck for a word? Take the fanciest English one you know and make it French. It works embarrassingly often.
False friends
A short list of words wear the disguise and mean something else. These are the , and they are worth learning as their own set, because the pattern will produce the wrong meaning every time.
| French | Looks like | Means | Instead, say |
|---|---|---|---|
| actually | currently | |
éventuellement | eventually | possibly | |
| assist | attend | |
| sensitive | | |
| library | bookshop | |
| rest | stay | |
| money | change, coins | |
| bless | wound, hurt | |
, .- At the moment, I work in..- I'm staying at home..- I sat an exam. (Passed it is.)
What to do next
- Take five English words in -ty or -tion and say them in French, with
. - Find one word with a circumflex and put the s back.
- Learn the false friends table as a list of eight.
