Adjectives in languages that have grammatical gender have to be in agreement with the nouns they modify. In Classical Arabic, however, some adjectives were commonly used in their base form (masculine singular) in front of feminine or plural nouns for emphasis, as opposed to Modern Standard Arabic where disagreement would be considered unusual.
Is there a recognized term in linguistics for adjectives being used in their base forms for emphasis?
Are there other languages that use/used adjectives similarly?
