Agreement with past participle in French can be a tricky subject for non-native speakers. It involves understanding the gender and number of the subject and how it affects the agreement of the past participle.

In French, the past participle is used to form compound tenses, such as the passé composé, and it must agree with the subject in gender and number. This means that if the subject is feminine, the past participle must also be feminine, and if the subject is plural, the past participle must also be plural.

For example, if the subject is “la fille” (the girl), and the past participle is “déçue” (disappointed), the agreement would be “la fille déçue” (the disappointed girl). This is because “déçue” agrees with the feminine gender of “la fille”.

Similarly, if the subject is plural, as in “les filles” (the girls), and the past participle is “déçues” (disappointed), the agreement would be “les filles déçues” (the disappointed girls). This is because “déçues” agrees with the plural number of “les filles”.

It is important to note that if the subject is masculine, the past participle will also be masculine. For example, “le garçon” (the boy) and “déçu” (disappointed) would agree as “le garçon déçu” (the disappointed boy).

There are some exceptions to this rule, such as with reflexive verbs or when the past participle is used as an adjective. In these cases, the past participle agrees with the subject regardless of gender and number.

It can also be helpful to remember that some common past participles such as “fait” (made) and “eu” (had) do not change when used with a subject.

In summary, agreement with past participle in French involves understanding the gender and number of the subject and how it affects the agreement of the past participle. While there are some exceptions and irregularities, following these guidelines will help ensure correct grammar in French.
