Should be "addressum" - please check in a dictionary for the exact form (as I'm only 99% sure). But addressare is latin meaning "to restore", etc. That means in this context, that you're address is something that others can use to refer to you. Several possible meanings for 'address' - the main ones: To speak to a group - Adire To address a letter - Epistolam inscribire An address (speech) - Alloquium An address (on a letter) - Inscriptio epistolae. If you mean 'address' as in street address, that came after the Romans were gone.
