dái

Dói is a Portuguese word meaning "hurts" or "aches." It is the third-person singular present indicative form of the verb doer, which means to cause pain or to ache; the infinitive is doer. The form dói derives from Latin dolere, and it is used in everyday speech to describe pain experienced by someone or something.

Usage and examples help illustrate its use. It is commonly found in sentences such as "A cabeça dói" (The head hurts) or "Dói-me o estômago" (My stomach hurts). The pronoun can be placed before the verb or attached to it, producing variants like "Me dói a cabeça" or "Dói-me a cabeça," depending on dialect or register. In Brazilian Portuguese, both "A cabeça me dói" and "A cabeça doi" constructions may appear, while European Portuguese more often uses clitic placement before the verb, as in "Dói-me a cabeça." The phrase "dói muito" means "it hurts a lot," and "Isso dói" translates to "That hurts."

Etymology and related terms: dói comes from the Latin verb dolere, which conveys the sense of pain or suffering. Related nouns include dor (pain) and doer as the verb from which dói is derived. The word is primarily used in medical, everyday, and literary contexts to describe physical or emotional ache.
