How to form the present tense using -ER verbs
Most verbs ending in -ER are regular, meaning that to conjugate them you can just follow a pattern.
Let’s take the verb parler (to speak) as an example.
First, you are going to want to chop off the -er at the end of the verb. This should leave with just the stem parl.
Then, you just add on the correct ending depending on the pronoun you are using.
je parle (I speak / I am speaking)
tu parles (You speak / You are speaking)
il/elle/on parle (He/She/One speaks/is speaking)
nous parlons (We speak / We are speaking)
vous parlez (You speak / You are speaking)
ils/elles parlent (They speak / They are speaking)
But, of course, there are exceptions to this rule as some verbs require you to change a letter or add a letter in order to keep the pronunciation from changing.
With verbs ending in -cer, the only change that really occurs is in the 1st person plural form (nous), the rest is conjugated as seen in the example above.
Let’s take the verb lancer (to throw) as our example.
The conjugation is as follows:
je lance (I throw)
tu lances (You throw)
il/elle/on lance ( He/She/One throws)
nous lançons (We throw)
vous lancez (You throw)
ils/elles lancons (They throw)
As you can see, in the 1st person plural form the “c” was swapped out for a “ç”. Why? Because otherwise the pronunciation would change and basically it’d throw the balance off and the French didn’t want that.
If we kept the “c” as it was, it would’ve been pronounced as “nous lankons” and honestly, it’s a no from me. It doesn’t sound right and so it must be changed.
Other verbs that follow this rule are:
commencer (to begin / to start / to commence)
placer (to put / to place)
And other verbs related to those, such as: balancer (to swing / to rock), recommencer (to start again / to begin again), s’élancer (to throw yourself forward), etc.
Just like in -CER verbs, the only change that occurs is in the conjugation of the 1st person plural form. This time, a letter is added, not swapped out.
Let’s use the verb manger (to eat) as our example.
The conjugation is as follows:
je mange (I eat)
tu manges (You eat)
il/elle/on mange (He/She/One eats)
nous mangeons (We eat)
vous mangez (You eat)
ils/elles mangent (They eat)
As you can see, we added an extra letter “e” into the 1st person plural form. Once again, it was added in order to keep the pronunciation from changing.
If we hadn’t added the extra “e” the “g” would take on the harder sound, like in the English word “gum”.
Other verbs that follow this rule are:
plonger (to dive / to plunge)
ranger (to tidy / to clean)
Related verbs also follow this rule, these include: déranger (to disturb / to bother / to interrupt), se changer (to get changed)
In the case of verbs ending in -ayer, -oyer, and -uyer, a letter is changed in the 1st, 2nd, and 3rd person singular form as well as the 3rd person plural form.
For our example, let’s use payer (to pay).
The conjugation is as follows:
je paie (I pay)
tu paies (You pay)
il/elle/on paie (He/She/One pays)
nous payons (We pay)
vous payez (You pay)
ils/elles paient (They pay)
This pattern can also be used with verbs like nettoyer (to clean) and essuyer (to wipe), you just take the “y” and replace it with an “i” in all forms except 1st and 2nd person plural.
However, with the verbs ending in -ayer there are also forms which do not swap out the “y” for an “i” (je balaie, je balaye (I sweep)) but they aren’t used often.
Bonjour! So this post is already very long and there’s still a lot to cover so I will do a part 2 and even a part 3 if I have to.
I hope that it isn’t too complicated to read and that I’ve got all of the information correct. If not, please let me know!
