incompréhensible

§ "Incompréhensible" vs. "difficile à comprendre"

Many English speakers learning French tend to overuse "incompréhensible" when they actually mean something is just "difficult to understand." While these phrases might seem similar, they carry different weights in French. "Incompréhensible" means something is absolutely impossible to grasp, with no way to make sense of it. Think of a complex mathematical equation without any explanation, or a language you've never heard before. It's beyond your capacity to comprehend.

Le discours du professeur était incompréhensible sans les notes. (The professor's speech was incomprehensible without the notes.)

On the other hand, "difficile à comprendre" simply means something requires effort to understand. It's challenging, but not impossible. Perhaps you need to read a text a few times, look up some vocabulary, or ask for clarification. It's within your reach with a bit of extra work.

Ce concept est difficile à comprendre, mais pas impossible. (This concept is difficult to understand, but not impossible.)

§ Using "incompréhensible" with emotions

Another common mistake is to use "incompréhensible" to describe emotions or behaviors that you find strange or illogical. While you might *not understand* why someone is acting a certain way, their behavior isn't usually "incompréhensible" in the literal sense of being impossible to grasp. Instead, you'd use phrases like "étrange" (strange), "bizarre" (weird), or "illogique" (illogical) to describe such situations.

Incorrect usage
Son comportement était incompréhensible. (Her behavior was incomprehensible.)

While grammatically correct, this sounds very strong, almost like her behavior defied all known logic or human understanding. More likely, you mean it was just unusual or you couldn't figure out her motivation.

Better alternatives
  • Son comportement était étrange. (Her behavior was strange.)
  • Je ne comprends pas son comportement. (I don't understand her behavior.)
  • C'est illogique. (It's illogical.)

§ Gender and number agreement with "incompréhensible"

Remember that "incompréhensible" is an adjective, and like most French adjectives, it must agree in gender and number with the noun it modifies. While "incompréhensible" ends in an 'e', making its masculine and feminine singular forms the same, you still need to add an 's' for plural nouns.

Singular
Le texte est incompréhensible. (The text is incomprehensible.)
La phrase est incompréhensible. (The sentence is incomprehensible.)
Plural
Les textes sont incompréhensibles. (The texts are incomprehensible.)
Les phrases sont incompréhensibles. (The sentences are incomprehensible.)

Forgetting this agreement is a common oversight, especially at the A2 level. Pay attention to the noun's form before using the adjective.
