Maybe during your study of French you’ve come across the pronunciation icitte instead of ici.
What’s the difference between icitte and ici?
Both icitte and ici mean the same thing: “here.”
The difference between the two isn’t one of meaning but of language level.
Icitte belongs to the level of language called populaire, just like the pronunciations moé and toé (for moi and toi).
You may have come across icitte before in song lyrics, stand-up comedy, or some forms of literature. However, you should know that icitte is felt to be an uneducated usage by certain speakers. It carries stigma — certain people disapprove of its use.
As a learner of French, your use of icitte may strike certain people as inappropriate or out of place, but this will depend on the people in your social circle.
Like moé and toé, I’d suggest you learn to recognise icitte but that you avoid using it yourself at this stage.
Ici, on the other hand, is used in all language situations and carries no stigma. You’ll never make a social blunder with ici.
