The rule that has no English equivalent is that individual names are accompanied by singular adjectives and plural nouns are accompanied by plural adjectives. Male names are described or limited by male adjectives, and female names are described or limited by female adjectives. Coordinating adjectives are adjectives that are just as important in describing a nostun, without one of them surpassing the others, and they are separated by commas. There are some adjectives that are known as variable adjectives that do not change in shape. Most of them are either unusual colors or words of foreign origin. An example is web ace in the web pegina (the website) and read web peginas (web pages). Sometimes a name can be used as an immutable adjective, but this practice is much less common in Spanish than in English. Being a Spanish student will rarely have the need to use immutable adjectives, but you should be aware that they exist so that they don`t confuse you when you see them. The noun adjective agreement is one of the most fundamental aspects of Spanish grammar: adjectives must correspond to the noun to which they refer in both numbers and sex.
Ha sido un d`a largo entre muchas semanas largas. (It was a long day between many long weeks.) The singular male largo is used with d`a, because d`a is a man and there is one, but the female pluralistic larga is used with Semanas, because Semana is female and there is more than one. Muchas are indeterminate male or female items. To find out if the adjectives used in a sentence are coordinated to use a comma between them, reverse the order of the adjectives or use the word and separate the two adjectives. If they are useful, they are coordinated and a comma is needed. No comma or conjunction and is necessary when adjectives stand in front of subtantifs or pronouns or separate non-coy adjectives belonging to different categories of adjectives. The adjectives are presented in bold. Just check my work:) 1. Fill out the next sentence. Juan`s estudioso.
