Adjective concord is concord of adjectives when they have to agree with the nouns they modify. This is not present in English grammar; when very occasionally found it is usually the result of French or Latin loan phrases.
|Singular||le petit prince||la petite princesse|
|Plural||les petits princes||les petites princesses|
