Questions & Answers about Lei deve inviare la ricevuta entro lunedì.
Why use entro here instead of fino a for "by Monday"?
Entro is used to set a deadline for a single event, meaning "by" or "no later than". If you used fino a ("until"), it would suggest an ongoing action that continues right up until Monday, which doesn't make sense for a quick, one-time action like sending a receipt.
The English translation says "You must", but doesn't Lei mean "She"?
Why isn't there an article before the day of the week, like entro il lunedì?
Could I use mandare instead of inviare to say "to send"?
