aumentei

Aumentei is the Portuguese verb form meaning "I increased" and serves as the first-person singular pretérito perfeito (simple past) of aumentar, which means to increase. It denotes a completed action in the past where the speaker increased something, such as quantity, size, or intensity. As a regular -ar verb, it follows the standard conjugation pattern for this class in the pretérito perfeito.

Conjugation: eu aumentei; tu aumentaste; ele/ela aumentou; nós aumentamos; vós aumentastes; eles/elas aumentaram. In modern Brazilian Portuguese, the forms with você and vocês are more common: você aumentou; vocês aumentaram. In European Portuguese, tú forms would align with aumentar as well, but regional usage varies and você remains common in many areas.

Etymology: aumentar derives from Latin augmentare, with augmentum as its root meaning growth or increase. The word entered Portuguese through historical contact with Old French augmenter, and developed into the modern verb aumentar and its related forms.
