demos
"Demos" in Portuguese means "we gave" (past tense of the verb "dar").
In this case, 'demos' precedes 'a partida,' meaning 'the start,' indicating the action of initiating or to set out on something, as part of 'dar.'
Demos a partida para a viagem de férias.
We started the journey for the vacation trip.
This usage of 'demos' is the first-person plural past-tense conjugation of the verb 'dar,' meaning 'to give' in Portuguese.
Na reunião, demos várias ideias interessantes.
In the meeting, we presented several interesting ideas.
Here, 'demos' conveys the act of giving — in this case, effort or dedication — in the past tense, again as part of the verb 'dar.'
