## 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.

1. 1

   A prefix is shown in capitals (PRE, SUR, RE…).
2. 2

   Five definitions come with it, one per word to find.
3. 3

   Submit one word per definition: it must start with the prefix.
4. 4

   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.

<summary>How is the Prefixo score calculated?

</summary>
