Learn Italian: È una donna.

In Italian, subject pronouns like lei (she) are usually dropped. Because the verb form è already means "is" (for he, she, or it), the listener can easily guess from the word donna (woman) that the hidden subject is "she". You could say Lei è una donna, but simply saying È una donna is much more common and natural.

Why does the word È have an accent mark?

The accent mark is very important! È (with the accent) is a verb meaning "is". If you write it without the accent as e, it means "and". The accent tells you it is the verb, and it also changes the pronunciation slightly to a more open sound.

Why use "una" instead of "un"?

Donna is a feminine noun, which you can usually guess because it ends in -a. In Italian, the word for "a" or "an" (the indefinite article) changes to match the gender of the noun. Because donna is feminine, we must use the feminine article una. If it were a masculine noun ending in -o, we would use un.

Could "È una donna" also mean "It is a woman"?

Yes, absolutely! Because the subject pronoun is left out, è on its own can mean "he is", "she is", or "it is". If you were pointing at a blurry photograph or a shadow in the distance and figuring out what it was, È una donna would naturally translate to "It is a woman."
