Put a negative around the past auxiliary
Negation must follow the structure of the whole verb group. « Elle a joué » becomes « Elle n’a pas joué ». Ne shortens to n’ before the vowel in a, and pas comes after the auxiliary. The participle joué stays after pas. Putting ne and pas around only the participle misses the conjugated centre of the sentence.
The same placement works with être in a non-pronominal perfect: « Elle n’est pas allée au parc ». Est remains the auxiliary, and allée still agrees with elle. Negating an event does not remove the agreement rule. The sentence denies a completed trip; it does not say that she never goes to the park in general.
Keep a time limit when the original text supplies one. « Hier, je n’ai pas joué » means I did not play yesterday. It is not the same as « Je ne joue jamais », which expresses never in a present-tense statement. A translation that replaces not yesterday with never changes the information.
Try this original leisure account: « Hier, j’ai lu dans le parc, mais je n’ai pas joué au football. » Lu is the participle of lire, introduced here as a checked word. The sentence reports reading and denies playing football. It does not establish whether the speaker likes or dislikes sport. A negative action statement is not automatically a preference.
A negative account can preserve a contrast between two completed past actions: « Hier, Léa n’a pas regardé le livre, mais elle a choisi les images. Hugo n’est pas allé au parc; il a préparé le texte. » In each negative, ne or n’ and pas surround the conjugated auxiliary, not the participle. The auxiliary still supplies the grammatical subject and tense information. Pas denies that particular action in the account; it does not mean never. The two positive clauses tell you what happened instead, so an answer claiming that nobody worked would ignore important evidence. The semicolon links clauses without making them the same action.
Transfer task: say that an explicitly female visitor did not go to the concert, but did look at the images. A model is « Elle n’est pas allée au concert, mais elle a regardé les images. » The negative does not remove the -e from allée; agreement and polarity are separate decisions. If the subject becomes two explicitly female visitors, use « Elles ne sont pas allées au concert, mais elles ont regardé les images. » The n’ contracts before est, whereas ne remains before sont. Regardé stays unchanged here. Reject « Elles sont allées ne pas »: it misplaces the negative and fails to negate the auxiliary in this finite perfect-tense clause.
Worked example: Make « Elle est allée au parc » negative.
Elide ne before est: n’est.
Place pas after est.
Retain allée and the destination.
Answer: Elle n’est pas allée au parc.
Check your understanding: Correct « Je ai joué ne pas hier ».
Answer: Je n’ai pas joué hier.
Why: Ne elides before ai, and pas follows the conjugated auxiliary. The sentence denies the event in the stated time.
