I have one sister and one brother.
'Sorella' = so-REL-la — double 'l'. 'Fratello' = fra-TEL-lo — double 'l'. Both clearly articulated.
Mention siblings naturally in a self-introduction when family comes up, or when someone asks about your background. Family information creates personal connection and is valued in Italian culture.
'Ho' is the first-person singular of 'avere' (to have). The indefinite article 'una' is used before feminine nouns starting with a consonant, 'un' before masculine nouns. This is a fundamental A1 structure.
Siamo in quattro in famiglia.
There are four of us in the family.
'Siamo in + number' — a natural way to describe family size.
Sono figlia/o unica/o.
I am an only child.
For those without siblings — 'unica/o' agrees with the speaker's gender.
Ho tre fratelli maggiori.
I have three older brothers.
'Maggiore' (older/elder) and 'minore' (younger) are essential family vocabulary.
Middle children are a running joke in Italian family culture — believed to be overlooked between the responsible firstborn and spoiled youngest. It's a light-hearted topic that many Italians can relate to.
