Bonjour,
Can I ask why the adjective in Maurice est un professeur excellent comes after the noun, while Vous êtes un mauvais avocat comes before? Maurice est un professeur excellent doesn't fall within the 5 categories listed in this lesson- https://kwiziq.learnfrenchwithalexa.com/revision/grammar/adjectives-usually-go-after-nouns-positions-of-adjectives
Merci!
