Learn Italian: La maglietta arancione è nuova.

In Italian, adjectives that end in -e in their singular form, like arancione (orange) or verde (green), have the same form for both masculine and feminine nouns. They only change their ending to -i for the plural.

What is the difference between maglia and maglietta?

Maglia is a general word for a shirt, sweater, or knit top. The ending -etta is a suffix that means something is small or cute. Adding it to maglia gives us maglietta, which is the specific everyday word for a T-shirt.

Why does the color arancione come after the noun?

Unlike English, where we say 'orange T-shirt', Italian adjectives that describe physical categories like colors, shapes, and materials almost always go directly after the noun they describe. So it becomes maglietta arancione.

Why is it nuova instead of nuovo?

An adjective must agree in gender and number with the noun it describes. Because maglietta is a feminine singular noun, the default masculine form nuovo changes to the feminine singular nuova.
