There are two (main) classes of adjectives in Latin:

- Some adjectives use the first declension for feminines (e.g. *Romana*, "Roman") and the second declension for masculines and neuters (e.g. *Romanus* and *Romanum*).
For adjectives like this masculine forms look different from feminine forms — with the exception of plural dative and ablative.
- Some adjectives use the third declension for all genders (e.g. *Mediolanensis/Mediolanensis/Mediolanense*, "Milanese", for feminine/masculine/neuter).
For these adjectives masculine and feminine forms look almost always the same.
The only exception can be in the singular nominative, but only for some adjectives (e.g. *celeris/celer/celere*, "fast", for feminine/masculine/neuter).
For *Mediolanensis* there is no difference between feminine and masculine.

In short:
**Some adjectives look different in masculine and feminine, some don't.**

This is also true in Romance languages.
In Italian you have the two forms *romana* and *romano* ("Roman") for the two genders (Italian has no neuter) but *milanese* ("Milanese") is both feminine and masculine.
