Changes in the stem form of some —er conjugation verbs

The stems of a number of verbs of the -er conjugation change their form when they are followed by an e. The majority of verbs ending in -eler or -eter double the final consonant of the stem when it is followed by -e in the present, future, conditional and present subjunctive:

	appeler	jeter
Present	j'appelle, tu appelles, il/elle appelle, ils/elles appellent	je jette, . . . etc.
Future	j'appellerai, . . ., nous appellerons, etc.	je jetterai, . . . etc.
Conditional	j'appellerais, . . ., nous appellerions, etc.	je jetterais, . . . etc.
Present Subjunctive	que j'appelle, que tu appelles, qu'il/elle appelle, qu'ils/elles appellent	que je jette, . . . etc.

The following verbs, however, do not double the final stem consonant, but change the first e to è: acheter, celer, ciseler, corseter, crocheter, démanteler, écarteler, fureter, geler, haleter, marteler, modeler, peler (together with verbs derived from these like congeler, dégeler, etc.):

	acheter
Present	j'achète, . . . etc.
Future	j'achèterai, . . . etc.

Other verbs which have an unstressed e in the syllable before the final –er also change that vowel to è in the same circumstances, for example mener, semer:

	mener
Present	je mène, . . . etc.
Future	je mènerai, . . . etc

Verbs which have an é in the syllable before the final -er change that vowel to è in the same circumstances, for example espérer, révéler:

	espérer
Present	j'espère, . . . etc.
Future	j'espérerai, . . . etc

Verbs of the -er conjugation whose stem ends in -y, for example employer, nettoyer, essayer, change the y to i in the same circumstances:

Employer

	employer
Present	j'emploie, . . etc.
Future	j'emploierai, . . . etc
