Pesquisar is a Portuguese verb that means to search or to research. In everyday language it refers to looking for information or objects, while in academic or professional contexts it denotes conducting systematic inquiry into a subject. The term can be used with various objects, such as informações, dados, fontes, or todo tipo de fenômeno to study.

Etymology and related forms: pesquisar derives from the noun pesquisa, which comes from Latin perscrutari (to examine thoroughly) and evolved through the development of Portuguese. Related terms include pesquisa (research or survey) and pesquisador/pesquisadora (researcher). The adjective form is investigative or related to pesquisa as a process of inquiry.

Usage notes: In Brazilian and European Portuguese, pesquisar is commonly used with the idea of seeking information, for example pesquisar na internet (to search on the internet) or pesquisar uma hipótese (to investigate a hypothesis). The noun pesquisa often refers to a study or survey, as in uma pesquisa científica.
