Questions & Answers about Emme salli kolmannen osapuolen käyttää henkilötietojasi.
Why is kolmannen osapuolen in the genitive case here?
This is the core rule for permission verbs like sallia (to allow) and antaa (to let). The entity being allowed to do something (the subject of the action) takes the genitive case, and the action itself is expressed with the 1st infinitive (käyttää).
How do you form the genitive kolmannen osapuolen from the nominative kolmas osapuoli?
Both words decline. The word kolmas (third) has the stem kolmante-, which undergoes consonant gradation (nt to nn) to become kolmannen. The word osapuoli (party) has the stem osapuole-, making the genitive osapuolen.
Could I use antaa instead of sallia in this sentence?
Grammatically, yes. You could say Emme anna kolmannen osapuolen käyttää... and the genitive + 1st infinitive structure works exactly the same way. However, sallia (to permit or allow) is much more formal than antaa (to let), which perfectly fits the legal or administrative tone of this sentence.
