"No, I don't want to know how to remember what largo means as a musical instruction..... I want to know what it means as part of a street name in Italy."
I was replying to the original post.
Largo as part of a street name means highway or byway - nothing to do with how I would recognise it for music. This is the case with a lot of Italian terms I think - they don't really mean what they do in the musical sense.
