French language Q&A Forum

I do not understand why appelée was used, and not appelé, and I do not think the explanation below is correct. Le Passé Composé here has nothing to do with Emma’s gender, as it surely has to agree with il. And why, then, would the suggested answers use téléphoné, and not téléphonée ?

I wrote 'rencontrerez' for the future of the verb rencontre, & I got it right in the fill-in-the-blank exercise Horoscope de l'année (Le Futur); however, it doesn't seem to fit into the pattern for either regular -er and -ir verbs in the future or -re and -dre verbs in the future, and it directed me to this page, so I'm confused.

"I gave it to him yesterday"

1)"Je le lui ai donné hier."    and      2) "Je lui ai donné hier."

Duolingo teaches the first translation above and it is also what is seen on some reliable French websites such as Lawless French. However I have also seen it translated as in number 2 and translators in particular seem to leave out the "le."

In the phrase, "curieuses boîtes", how do you know to place curieuses before the noun.

Thanks

Why are we adding de in front of  mieux in the sentence il n’y a rien de mieux  que d’’ouvrir..... 

« Combien d’enfants avez-vous? »

Can’t figure out why this is right. Enfants is plural.

Wouldn’t you say « J’ai des enfants. »

"Avez-vous ton crayon?"  This sentence here mixes a formal (or plural) pronoun with a familiar possessive adjective, which doesn't feel correct.  Could I get  confirmation that "ton, ta, tes" works for whomever is directly spoken to?
