Pronouns are used when you get tired of repeating nouns. There are many different types of French pronouns – try these links for detailed lessons and examples of each type.
Some French verbs do not allow their indirect objects to be replaced by pronouns; instead, the preposition must be maintained after the verb along with the indirect object.
As you might guess from their name, adverbial pronouns are caught between two worlds: they are pronouns in the sense that they replace nouns, and at the same time they are adverbs representing a place, a quantity, or the object of a proposition. French has two adverbial pronouns: en and y.
Grammatical agreement is a vast topic - and one of the banes of French students. While in English we have a few pronouns and adjectives that indicate gender and number (e.g., he/him/his and she/her/hers), in French, agreement is found in 5 of the 8 parts of speech.
When the subject of a French verb is nous, vous, ils, or elles, it's obvious which verb conjugation you need, because those plural pronouns are included in verb tables. But it's a bit trickier with compound subjects made up of multiple names, nouns, and/or pronouns. In these cases, you need to take a moment to figure out which plural subject pronoun those items add up to, so that you know what to conjugate for.
Compound tenses and moods are verb forms which are conjugated with two parts: a helping / auxiliary verb and a past participle, as in J'ai dansé. The word order can get a little complicated when additional grammatical structures like object pronouns and negation are introduced.
Connectives are links: they combine words, phrases, or sentences. Connectives do not constitute a single part of speech, but rather a category of terms including all conjunctions and prepositions as well as certain types of adverbs and pronouns used in this way.
Demonstrative pronouns (celui, celle, ceux, celles) replace a specific noun that was mentioned previously. In French, they must agree with the noun(s) in number and gender.
A direct object is a noun, whether person or thing, that someone or something acts upon or does something to. In both French and English, direct objects are often replaced with direct object pronouns (COD): me, te, le, la, nous, vous, les.
