Locative

The locative case is a Latin grammatical case which indicates a location used exclusively for cities and small islands. It corresponds to the English preposition "in".

Here are the basic and very general rules for making a locative case of cities:

• If a city's name ends in "-us" or "-um", then the locative ends in "-i".

"Corinthus" becomes "Corinthi",

"Mediolanum" becomes "Mediolani".

• If a city's name ends in "-a", then the locative ends in "-ae".

"Roma" becomes "Romae".

• If a city's name ends in "-i" or "-ae", then the locative ends in "-is".

"Delphi" becomes "Delphis",

"Athenae" becomes "Athenis".
