Stem-Changing Verbs

In a previous lesson, we explored how the accent grave (è) and accent aigu (é) interact within a single word. But how do these accents function when conjugating certain -er verbs? Specifically, why do verbs like acheter (to buy) take an accent grave (achète), while appeler (to call) has a double l (appelle) in the present tense? Let's find out!

When verbs like these lose their -r infinitive ending during conjugation, a silent e remains in the last syllable, leaving us with two consecutive silent e's separated by a single consonant: "achete," "appele." Since French phonology typically avoids having two consecutive silent e's, the spelling must be altered—via an accent or a doubled consonant—to maintain correct pronunciation. Verbs that do this are known as stem-changing verbs.

One group of French -er verbs, including appeler (to call) and jeter (to throw), have a double consonant in certain conjugated forms. Basically, for the je, tu, il/elle and ils/elles conjugations, you take the verb stem (what’s left after you take out the -er of the infinitive), and double the final consonant: appell-, jett-. Then it's just a matter of adding the usual appropriate endings. But note that the stem only changes in the je, tu, il/elle, and ils/elles forms, not nous or vous. So you have j'appelle and tu jettes, but nous appelons and vous jetez.

The change occurs in the present and future tenses, and the conditional mood:

Je m'appelle Nelly.

My name is Nelly.

Et d'ailleurs, il est prévu dans "x" siècles que la Moselle ne se jetterait plus dans le Rhin.

And incidentally, it has been predicted in "x" number of centuries that the Moselle supposedly won't flow into the Rhine anymore.

In addition, there is a second group of verbs that don’t double consonants, but require an accent grave on the penultimate e instead. Common verbs in this group include acheter (to buy) and se lever (to get up):

Tu achètes une douzaine d'œufs.

You buy a dozen eggs.

Elle se lève à neuf heures.

She gets up at nine.

As with the first group, the verb stem doesn't change in the first- and second-person plural (nous and vous), as the final syllable is now stressed:

Donc c'est un objet en terre cuite, bien sûr, ce que nous achetons

So this is a terra cotta object, of course, which we are buying

Vous vous levez très tôt.

You get up very early. 

Likewise, this rule also applies to the conditional mood and future tense:

Tu achèteras une douzaine d'œufs.

You will buy a dozen eggs.

Elle se lèverait à neuf heures tous les jours si elle avait un réveil.

She would wake up at nine every day if she had an alarm clock.

What happens when an -er verb has an accent aigu in it, as in céder (to cede)? The é changes to an è! 

Les Autrichiens cèdent une partie de leur territoire

The Austrians cede part of their territory,

As mentioned in a previous lesson, the 1990 spelling reform changed some accent rules, but these are not universally applied. So, for instance, you will see both je cèderai (per the spelling reform) or je céderai:

Idem pour je céderai.

Likewise for "I will give in."

Unfortunately, there's no hard and fast rule to determine whether a stem-changing verb takes a double consonant or an è. But to familiarize yourself with the full list of them, click here. Just remember that in all of these cases, the stem only changes in certain persons (je, tu, il/elle, ils/elles) and in certain tenses/moods (present, future, conditional). Thanks for reading!
