entendeu

Entendeu is a conjugated form of the Portuguese verb entender, meaning "to understand." It is the third-person singular pretérito perfeito (preterite) of entender, and it is commonly used to refer to a past understanding. In Brazilian Portuguese, entendeu is also the typical form used with the subject você (you), as you-which uses third-person agreement: "Você entendeu?" means "Did you understand?" In Portugal, the corresponding informal second-person singular form is "tu entendes" in the present, and the preterite is "tu entendeste," while "você entendeu" is also understood in many registers.

Usage and nuance: entendeu can function as a straightforward past statement, as in "Ele entendeu a explicação" (He understood the explanation), or as a question, "Entendeu?" meaning "Understood?" It is common in conversation and can carry emphasis or irony depending on tone. The form is widespread across dialects and registers, though actual usage of tu/ você forms varies regionally.

Etymology and related forms: entender derives from Latin intendere, via Old Portuguese entender, with the sense shift from “to stretch toward” or “to intend” to “to understand.” Cognates include Spanish entender and French entendre, reflecting a shared Romance-language heritage.

Examples:

- Você entendeu o que eu disse?

- Ele entendeu a tarefa.

- Entendeu! (colloquial acknowledgment or mild sarcasm)

Overall, entendeu is a common, neutral verb form used to express or inquire about understanding in past contexts.
