Learn Hardcore French: Je monte l'escalier avec Paul.

In French, using l’escalier emphasizes a specific staircase—likely the one in the location or situation you’re talking about. Saying un escalier would refer to any staircase. Since you already know which staircase is being discussed, French uses the definite article l’.

Why is the verb in the present tense monte rather than something like montons or montent?

The verb form must match the subject je (meaning I). In the present tense, je monte is the correct conjugation for monter (to go up, or to climb). If the subject were nous (we), it would be nous montons, and if the subject were ils or elles (they), it would be ils/elles montent.

Why can we say Je monte l’escalier without adding sur or dans before l’escalier?

In French, monter can be used transitively with an object, so monter l’escalier literally means to climb the staircase. You don’t need a preposition like you might in English (e.g., up the stairs). The construction monter + direct object is correct and common in French.

What is the role of avec Paul at the end of the sentence?

Avec means with, so avec Paul indicates that Paul is accompanying the speaker. The phrase Je monte l’escalier avec Paul tells us that the person speaking and Paul are going up the stairs together.

Can I use the phrase Je monte l’escalier avec Paul in different tenses?

Absolutely. In the passé composé (compound past), for instance, you would say Je suis monté(e) l’escalier avec Paul (if you need the e depends on the speaker’s gender). In the future tense, it would be Je monterai l’escalier avec Paul. The meaning remains the same—I go up the stairs with Paul, just shifted in time.
