PhraseA1

Ich bin ... Jahre alt.

/ɪç bɪn ˈjaːʁə alt/

I am ... years old.

Usage Note

'alt' here means 'old' in the sense of age, not 'old' as in outdated. Always include 'Jahre' — saying just 'Ich bin zwanzig' sounds incomplete.

Ich bin zwanzig Jahre alt.

I am twenty years old.

Ich bin dreißig Jahre alt.

I am thirty years old.
