concluíste
Concluíste is the second-person singular form of the verb concluir in the pretérito perfecto simples (simple past) of Portuguese. It translates as "you concluded" or "you finished." This form appears with the pronoun tu and is primarily used in European Portuguese and in some Brazilian regional varieties. In standard Brazilian Portuguese, the corresponding second-person form is "você concluiu."
