This is the 90th most frequent French word.
eu
The French word "eu" is the past participle of "avoir," meaning "had" in English.
In this sentence, 'eu' represents the past participle of the verb 'avoir' used in the passé composé to indicate that the speaker had an idea.
J'ai eu une bonne idée pour le projet.
I had a good idea for the project.
Here, 'eu' is again the past participle of 'avoir', this time used to form the past conditional mood, indicating a hypothetical situation in the past.
Il aurait mieux fait s'il avait eu plus de temps.
He would have done better if he had had more time.
In this context, 'eu' serves as part of the passé composé construction to describe the receipt of the response as a completed action in the past.
