le préfixe + la racine + le suffixe

Bonjour à tous!

Ok, I have to start organizing my notes from the two french oral workshops. As my teacher, Éric, taught in a not-very-organized way, so are my notes... But I still think he is the best teacher in AF.

In each lesson, he first asked us questions or gave us a situation and we had to say something (a few sentences maybe). Then, he tried to correct our mistakes and explained some grammar rules or introduced some sentence patterns.

Sur la liste, il y a quartre personnes inscrites.

"Inscrites" is an adjective (f / pl) which comes from the verb "inscrire".

"ins" is the prefix (le préfixe) whereas "crire" is the root (la racine).

"inscrire" = "écrire dans une liste"

Then, he further explained the use of "inscrire" before telling us more about le préfixe et le suffixe.

We usually use "inscrire" with "se", ie "s'inscrire", which is un verbe réflexif / pronominal.

ex. Je m'inscris dans le cours d'oral.

If you don't use it with a reflexive pronoun, make sure there is a direct object (complément object direct, ie COD) in your sentence.

ex. J'inscris mon fils dans le cours d'oral.

In this sentence, "mon fils" is the COD.

Ok. Let's go back to le préfixe et le suffixe. 

He said that we can add le préfixe "in" to form opposites and le suffixe "able" to turn verbs into adjectives. 

ex. accepter (v) => (in)acceptable (adj)

Of course, we can't simply add "able" after an infinitive. Here is the formula:

ex. accepter => (nous) acceptons => - ons + able => (in)acceptable

ex. vendre => (nous) vendons => - ons + able => (in)vendable

ex. habiter => (nous) habitons => - ons + able => (in)habitable

ex. utiliser => (nous) utilisons => - ons + able => (in)utilisable

However, please pay attention if the word starts with "b", "m" or "p". Instead of adding le préfixe "in", we add "im":

ex. boire => (nous) buvons => - ons + able => (im)buvable

ex. mettre => (nous) mettons => - ons + able => (im)habitable

ex. manger => (nous) mangeons => - ons + able => (im)mangeable

ex. porter => (nous) portons => - ons + able => (im)portable

Great! That's all for today. Au revoir!
