mess v. messa
In English, a mess is a disorderly, cluttered, and often dirty condition. In Italian, la messa is a public celebration of the Eucharist in the Roman Catholic Church: our English word, Mass. No Italian would forgive you for associating her messa with a mess. That would border on offensive. Use the words confusione or casino when translating from English.
Eng) The construction of the new building across the street is causing a mess.
It) La costruzione del nouvo edificio dall'altra parte della strada crea della confusione.
