Spanish (Spanish: Espa? Ol) belongs to the Romanesque family of Indo-European languages. According to the number of speakers of the first language, about 437 million people use it as their mother tongue, making it the second largest language in the world, second only to Chinese. The number of people who use Spanish accounts for 4.84% of the world population, and the total number of users of the first language and the second language is nearly 570 million. Mainly used in Spain and Latin America (except Brazil, Belize, French Guiana and Haiti).

Grammar:

Spanish is a inflectional language. After a long period of evolution, its morphological changes have been greatly simplified. Except for pronouns as subject and object and their reflexive forms, the Latin case system has almost disappeared. Nouns are masculine and feminine, but neutral traces can be seen in some structures. Add -s or -es to the complex number. Adjectives have a harmonious relationship with nouns in grammar, and the suffix changes are the same as nouns. Verbs still retain many inflections, but they are regular. Because the suffix of the verb is enough to express the person, the subject is often omitted.

Nouns and adjectives have singular and plural forms. Usually, -s (words ending in vowels) or -es (words ending in consonants) are added after the root. Nouns and adjectives in sentences should be consistent in sex and number.
