Verified answer

J'ai voyagé à Paris. (Don't forget those accents! For verbs that take "avoir" as their auxiliary, the participle remains the same for singular and plural, masculine and feminine.)

- or -

Je suis allée à Paris. (If you're a girl. The verb "aller" takes "être" as its auxiliary, so the participle must agree in number and gender with the subject.)

First one is correct.

I don't what you are trying to say in the second sentence, there is only one form of passé composé

and the verb voyager always takes avoir, are you trying to say the feminine form of the first sentence in your second one ? If yes it remains the same when the helper verb is avoir you don't add the "e".

So a girl speaking would say j'ai voyagé.. or je suis allée..

A guy would say j'ai voyagé or je suis allé.

first one is correct. the second one, if you're a female then you add the extra -e at the end, if you're a male then keep it at the e with the thing on top. If there are several add an -s, and several females add -es. Also for the second one, you need to add a form of etre. The etre congregation for Je is suis, so it'll be Je suis voyagee a Paris. Here are the other congregations:

Je - Suis

Tu - Es

Il/Elle - Est

Nous - Sommes

Vous - Etes (With the triangle thing on the first E)

Ils/Elles - Sont

Good luck!!

General rule

If you use the verb être (je suis, tu es, il est, nous sommes, vous êtes, ils sont) you conjugate your participe passé with the subject.

(WTF? here's an example)

Mon frère est tombé sur la glace (my brother fell on the ice)

step 1: verb=être

step 2: qui (ou quoi) est tombé? = mon frère

step 3: conjugate tombé accordingly = tombé

(singular: masculine: é, feminine: ée

plural: masculine : és, feminine: ées)

ma soeur est arrivée de voyage

mes parents se sont arrêtés en route

mes amies se sont maquillées pour la soirée

If you use the verb avoir (j'ai, tu as, il a, nous avons, vous avez, ils ont) you conjugate your participe passé with the *complément d'objet direct* if it's in front of the participe passé (sorry don't know that one in english

ex: J'ai voyagé à Paris

step 1: verb= avoir

step 2: (cod) you ask the question: j'ai voyagé QUOI?

step 3: no answer!, so voyagé stays 'neutral'

ex:

Les fleurs que tu m'as données sont mortes

Tu m'a donné QUOI? les fleurs (before p.p. = conjugate verb with fleurs (feminine plural: données))

Makes sense?
