Adjectives
Basic properties of Italian adjectives:
- They agree in gender and number with the nouns not only when they modify the nouns but also when they are in the predicate of the nouns*.
*Questa è una casa bella. This is a nice house.
*Questa casa è bella. This house is nice.
- Its typical position is after the noun
- The ending is either -a/-o or -e in singular
Adjectives ending in –a/-o
| singular | plural | English (singular) | 
| una casa nuova | due case nuove | a new house | 
| un libro nuovo | due libri nuovi | a new book | 
| una nave nuova | due navi nuove | a new ship | 
| un signore alto | due signori alti | a tall man |
