We are going to explore these “I” adjectives together and how they can spice up your sentences. And don’t worry, I won’t just throw a list at you in a robotic way… Get ready to discover cool words, fun anecdotes, and some linguistic gems that you can bring out at parties to shine like an aspiring lexicographer!


Why be interested in adjectives starting with “I”?

Adjectives are the secret sauce of the French language. They add depth to our sentences, express emotions, and make our speech more impactful. But those starting with “I”, they have something extra. Why? Because they are less common and therefore more stylish!

When you say “he is an irreproachable individual”, it sounds more impressive than “he is a good guy”, doesn’t it? Add a little “inimitable,” “ruthless,” or “ingenious” to your vocabulary, and voilà, you’re elevated from a regular conversation to a master of rhetoric.


The most used “I” adjectives (and those that no one knows)

Alright, let’s get down to business. Here is a list of adjectives starting with the letter “I” and how to use them to maximize your charisma quotient.

Must-know (those you already know, but are useful)

  • Unforgettable: Like that last restaurant where you paid €100 for an empty plate.
  • Incredible: To be used to describe everything from a sports feat to your cat’s ability to sleep 20 hours a day.
  • Ingenious: When someone finds a solution to a problem with three pieces of string and a paperclip, MacGyver style.
  • Impressive: Your friend who can solve a Rubik’s cube in 10 seconds deserves this qualifier.
  • Irreproachable: Your alibi when you claim you didn’t eat the last piece of cake.

Less known (but deserve more love)

  • Idoine: It’s just a stylish word for “perfectly suitable.” Ex: “A mojito is idoine for a summer evening.”
  • Inextinguishable: That which cannot be extinguished, like your passion for raclette.
  • Irascible: That colleague who gets angry as soon as the coffee machine breaks down.
  • Impavid: The one who remains stone-faced in front of a horror film while you scream at every jump scare.
  • Immutable: That friend who refuses to change their hairstyle since 2003.

How to properly use “I” adjectives in your sentences?

Now that you have a nice list of “I” adjectives, you still need to know how to place them correctly in a sentence. Here are some tips:

  1. Don’t overdo it: A text with too many adjectives is like a dish that’s too spicy… it stings the eyes!
  2. Vary your pleasures: Alternate between common adjectives and rarer ones to avoid sounding like you’re reciting a dictionary.
  3. Play with contrast: Saying “He is irresistibly irascible” creates a humorous effect and grabs attention.
