"Tu lui as tout raconté, alors la surprise est gâchée."

Translation: You told her everything, so the surprise is ruined.

[4ledger]

You told him everything so the surprise is spoilt - marked wrong. Pourquoi?

[tony852474]

why gachee and not ruinee?

[V3WW9ody]

"You told everything to her, so the surprise is ruined." was not accepted. I don't see any substantive difference between my sentence and the one Duo wants.

[emms68]

They don't accept spoiled too.

[JeanShrops]

Or even spoilt (UK English)

[eoxathens-gmail]

Why her and not him? How can we tell?

[FranM2]

You can't tell and both are accepted.

[deactivated user]

This exact sentence has recurred in every level and "him" is NEVER accepted. Years of complaints and reporting have been ignored.

[Bumbersnatch]

I used him and it was accepted. I suspect you had a different mistake.

[mammad99]

@eoxathens-gmail They are both correct.

[deactivated user]

They're both correct but "him" has been marked wrong for a year or more despite our
cries of despair.

2021-08-03: you told him everything, therefore the surprise is ruined --still refused

[Bumbersnatch]

There's nothing wrong with him in your sentence, but therefore translates as donc.

I've used spoilt or spoiled on every other occasion for gâché(e) and it's been accepted but not this time. Ruined is wanted! Reported it
