How to play?

A prefix — RE, SUR, ANTI… or just the start of a word — and five clues. Behind each clue hides a word that begins with those letters. French word-building becomes a playground.

A prefix is shown in capitals (PRE, SUR, RE…).
Five definitions come with it, one per word to find.
Submit one word per definition: it must start with the prefix.
Find all five words to win the round.

Why play?

Shows how words are actually built.
Improves spelling through logic rather than rote learning.
The definitions surface rare, satisfying words.

Tips

Each word's length is shown and the prefix is already filled in: subtract its letters to know exactly how many are left to find.
The prefix isn't always a grammatical one: it can simply be a two-letter word start. Don't limit yourself to words built with RE, PRE or ANTI.
Definitions are two to four words long, crossword-style. Look for the exact term they sum up, often a synonym or a noun rather than a paraphrase.
After a wrong guess, correctly placed letters after the prefix stay locked in orange. Make the most of them before spending a joker, which costs points.
Ignore accents: the keyboard has none and É is typed as E, so there's no need to choose between PRÉ and PRE.

Frequently asked questions

How do you play Prefixo?

A prefix appears with five short definitions. For each one, find the word that starts with that prefix: its length is shown and the prefix is already in place. Tries are unlimited and you pick the order. Find all five words to win. The words are in French.

Is Prefixo free to play?

Yes. Prefixo is completely free and runs in your browser, on desktop or mobile, with nothing to download. You can play today's grid without an account; a free account unlocks the archive of past days, and SIWA+ (€18 a year) removes ads and adds advanced stats.

What counts as a prefix in Prefixo?

It is the beginning shared by all five words. It is often a genuine French prefix such as RE, PRE, SUR or ANTI, but it can also be a plain two-letter word start. The definition is what tells you which word is expected.

How is the Prefixo score calculated?

Your score out of 1000 rewards finding the words with few mistakes. Every wrong guess and every joker costs points. Time matters too: you earn a bonus for beating the reference time and a penalty for being much slower. You also get 1 to 3 stars.

What can I do if I can't find a Prefixo word?

Use a joker: it reveals a letter of the word you didn't know yet, at the cost of a few points. You can also move on to another definition and come back later. If you give up, your score for the game is capped.
