Literal translation
good day, good folk…
Meaning
good day, good folk, forgive me if I'm mistaken
Explanation
The full formula, bounjou bràvi gènt, escusas-mi se mi tróumpi, good day, good folk, forgive me if I'm mistaken, is a collective greeting addressed to a whole roomful of people upon entering a public place, a shop, or a café, with no one person singled out. The adjective brave here carries its older sense of good, honest, worthy of respect, while gènt means people in a broad sense, so the whole phrase amounts to a warm greeting to the entire gathering present. The apology that follows, se mi tróumpi, if I'm mistaken, adds a touch of humility and slightly old-fashioned politeness, as if excusing in advance any awkwardness in a general greeting that might not quite suit anyone in particular. The register is pleasant and convivial, delivered with a smile in the social exchanges of village or neighborhood life, marking a warm entrance, far from a stiff formula of politeness.
