Learn Hardcore Spanish (Spain): Bailar trae alegría.

Bailar means "to dance." Trae is the third person singular present form of the verb traer (meaning "to bring"). Alegría translates as "joy." So literally, the sentence means "To dance brings joy," which is naturally rendered in English as "Dancing brings joy."

Why is the verb bailar in the infinitive form instead of being conjugated?

In Spanish, the infinitive can function as a noun. When an activity in general is the subject of a sentence—like dancing in this case—the infinitive is used without conjugation. It represents the idea of the action as a whole, rather than a specific instance.

How does subject–verb agreement work when the subject is an infinitive?

Even though bailar is an infinitive, it is treated as a singular, abstract noun. Therefore, the verb trae is correctly conjugated in the third person singular form to agree with that singular subject.

Why is there no article before alegría?

When referring to abstract concepts or general ideas—such as joy in this sentence—Spanish often omits the article. Here, alegría expresses a general quality or state, so no definite or indefinite article is needed.

Is the structure "Infinitive + Verb + Noun" common in Spanish, and what does it express?

Yes, this structure is common in Spanish for stating general truths or opinions. Using an infinitive as the subject emphasizes the activity or concept in an abstract, general sense, while the verb and complement explain what that activity does or what quality it has—in this example, that dancing brings joy.
