La réponse
The Crostic clue “Empêcher de progresser” is answered by ENRAYER. It is 7 letters long.
If the answer above does not fit your grid, check the puzzle it came from — the surrounding answers usually make the right one obvious. Every puzzle this clue appears in is linked below, and you can browse the whole game from the Crostic answers hub, which covers 4,378 puzzles.
Clues in Crostic are reused far more often than people expect, which is why a clue you have already solved can reappear months later in a different puzzle. When the same wording carries more than one answer, letter count is what separates them: this page lists each candidate with its length so you can match the one your grid needs.
Every answer here is taken from the live game rather than copied from another answers site, and re-checked when the developer updates a puzzle. If ENRAYER no longer matches what you see on screen, say so in the comments below and it gets looked at — reader reports are usually how a changed puzzle is spotted first. You can also work backwards from the puzzle itself using the links above, which is often quicker than searching clue by clue.
