Questions & Answers about Ellos leen muchos libros.
How do we make the word libro plural in this sentence?
Why is the word for "many" written as muchos?
In Spanish, describing words (adjectives) must match the noun they describe. Because libros is masculine and plural, the word mucho changes to match it, becoming the masculine plural muchos.
Why does the verb leen end in an -n?
The base verb is leer (to read). When talking about "they" (ellos or ellas) or "you all" (ustedes), present tense verbs end in an -n. So, lee (he or she reads) becomes leen (they read).
Could I say this sentence without the word Ellos?
Yes! Because the verb leen is already in the plural "they" form, Spanish speakers often drop the subject pronoun. You can simply say Leen muchos libros and people will easily understand what you mean.
