Question

Why do we place the adjective before the noun in some sentences, and after the noun in some sentences?

Accepted Answer

Bonjour Jurgen,
In French, most adjectives will be place after the noun. But there are a lot of exceptions too. It's also important to know that the position of an adjective can change its meaning:

Before the noun: Often figurative or subjective.
After the noun: Often literal or objective.

Here's a famous mnemonic tip to help you remember adjectives that come before the noun: you can call them the BAGS adjectives, which stand for
Beauty (joli/beau)
Age (vieux/jeune)
Goodness (gentil/méchant)
Size (grand/petit)
