Questions & Answers about Ich zeige ihnen den Park.
ihnen is the dative plural pronoun meaning to them.
The verb zeigen (to show) normally uses:
- a dative object for the person: ihnen (to them)
- an accusative object for the thing: den Park (the park)
If you used sie instead:
- sie (plural) is accusative or nominative, not dative.
- Ich zeige sie den Park is ungrammatical, because the person must be in the dative case after zeigen.
So:
- ich zeige ihnen den Park = I show them the park (correct)
- ich zeige sie den Park = wrong in standard German
Lowercase ihnen = to them (3rd person plural, dative).
Uppercase Ihnen = to you (formal Sie, singular or plural, dative).
So:
- Ich zeige ihnen den Park. → I show them the park.
- Ich zeige Ihnen den Park. → I show you (formal) the park.
The polite pronoun Sie/Ihnen/Ihr is always capitalized in the middle of a sentence.
All other personal pronouns (ich, du, er, sie, wir, ihr, sie) are written in lowercase (except at the beginning of a sentence).
