"Medium" is somehow translate to "Media" even though the locale is default "en_US" and no .strings file

Aha! Morphology, there is so much going on with this:

public enum InflectionRule {

    case automatic

    case explicit(Morphology)

    public init(morphology: Morphology)
}

Morphology has: GrammaticalGender, PartOfSpeech, GrammaticalNumber :thinking:

Maybe Morphology GrammaticalNumber is how to tell it to use which plural spelling?

Here is how to ad-hoc specify this in source code:

Text("^[\(2) ^[\(String(localized: "medium"))](morphology: { partOfSpeech: \"noun\" })](inflect: true)")   // 2 media b/c automatic grammar agreement
