There is a lesson on Lawless French about personality/character traits that you might find useful:

https://www.lawlessfrench.com/vocabulary/personality/

As you'll see in the lesson, adjectives are used to describe personality/character traits, so all of the Kwiziq lessons on adjectives will apply to personality/character trait adjectives as well. You can find a list of adjective-related lessons in the Library:

Hope this helps :)

I was born speaking French and Italian but over 30 of english I lost some dexterity about my two first languages which I still speak very appropriately!
