Question 1

What is the difference between the stem and the infinitive?

Accepted Answer

The infinitive is the complete, unaltered dictionary form of the verb, containing both the core meaning and the group identifier (e.g., parler). The stem, or radical, is what remains after you strip away the infinitive ending (e.g., parl-). The stem acts as the base foundation to which you attach new tense-specific endings to match the subject pronoun. While regular verbs use a consistent stem, irregular verbs often completely change their stem depending on the tense being used.

Question 2

Why are there so many silent letters at the end of French verbs?

Accepted Answer

The silent letters in French verb conjugations are linguistic fossils. Hundreds of years ago during the Middle Ages, endings like the "-s" in tu parles or the "-ent" in ils parlent were fully pronounced. Over centuries of spoken evolution, the French people naturally dropped these sounds to speak faster and more fluidly. However, when the Académie Française standardized the written language in the 17th century, they chose to keep the historical Latin-based spelling, resulting in a modern language where the written conjugation is much more complex than the spoken reality.

Question 3

How do I know whether to use avoir or être in the passé composé?

Accepted Answer

The default rule is that approximately 95% of all French verbs use avoir as their auxiliary verb. You only use être for a specific, closed list of verbs. These are predominantly verbs that indicate motion or a change of state, famously memorized using the acronym DR & MRS VANDERTRAMP (Devenir, Revenir, Monter, Rester, Sortir, Venir, Aller, Naître, Descendre, Entrer, Rentrer, Tomber, Retourner, Arriver, Mourir, Partir). Additionally, all pronominal/reflexive verbs (verbs using se, like se laver or se réveiller) automatically require être.

Question 4

When exactly should I use the imparfait instead of the passé composé?

Accepted Answer

You should use the imparfait to describe ongoing, continuous, or habitual actions in the past where the exact beginning and end are not defined (e.g., "I used to play piano," "It was raining," "I was happy"). You use the passé composé for specific, isolated, completed events that occurred at a specific point in time and are now finished (e.g., "I played piano yesterday at 5 PM," "It started to rain," "I became happy"). Think of the imparfait as the background scenery and the passé composé as the specific actions taking place on stage.

Question 5

Do I really need to memorize all 25 irregular verbs?

Accepted Answer

Yes, absolutely. The 25 most common irregular verbs—such as être, avoir, aller, faire, dire, and pouvoir—make up a massive percentage of daily spoken and written French. Because they are used so frequently, you cannot rely on regular conjugation formulas to guess their forms. Failing to memorize these specific verbs will severely cripple your ability to form basic sentences, as they are essential for expressing fundamental concepts like wanting, being able to, having to, and going.

Question 6

Why do -RE verbs drop the 'e' in the futur simple?

Accepted Answer

In French phonetics, having two vowels crash into each other is generally avoided because it disrupts the flow of speech. The endings for the futur simple all begin with a vowel (-ai, -as, -a, -ons, -ez, -ont). If you kept the "e" at the end of an -RE infinitive like vendre, you would end up with vendrea, which is phonetically awkward. By dropping the final "e" to create the stem vendr-, the consonant "r" connects smoothly with the vowel of the ending, creating a fluid sound like vendra.
