Not the parent, but you use a translation format like `translations("INVITE_USER", {gender_of_host, num_guests})`

Then you will have an algorithm that knows to translate based on some rules - like the ICU messages format - https://unicode-org.github.io/icu/userguide/format_parse/mes...

In the link there's an example of how such rules look like (they'll be different for each language)
