introduziste

Introduziste is a Portuguese verb form, specifically the second-person singular preterite (pretérito perfeito simples) of the verb introduzir, meaning you introduced. It is used with the subject pronoun tu and corresponds to a completed action in the past. In many Brazilian varieties, the corresponding form for past tense with you is introduced by você, as in você introduziu, rather than tu introduce.

Morphology and usage notes: The form is built on the stem introduz- plus the ending -iste, which is characteristic of the tu form for -ir verbs in the preterite. The correct spelling is introduziste. For contexts where the pronoun você is used instead of tu, the equivalent past tense form is introduziu (ele/ela você).

Etymology and meaning: Introduzir comes from Latin introducere, meaning to lead in or to introduce. In Portuguese, the verb acquires several senses beyond simply placing something into a space, such as presenting a topic, introducing a person, or initiating a procedure or system.

Context and usage examples: Tu introduziste o tema na reunião. Quando introduziste as novas regras, todos entenderam. In modern Brazilian Portuguese, speakers often prefer você introduziu, but introduziste remains correct in dialects that maintain tú as the subject.
