Message Report.turn.playerNation („Däm %player% sing / ier {{tag:country|%nation%}}
“) would need to have GENDER support.
Why? %player% is the name of the player and %nation% is the player's nation.
Because %player% and %nation% have genders, and a Colognian genitive (%player%s) requires two words, one depending on the gender and the numerus of %player%, the other depending on the gender and the numerus of %player% plus the gender and the numerus of %nation%. Numerus can be assumed to be singular for either, that narrows possible choices down to 5 (unknown gender included)
Of course, one can always choose to use a wording for the "all genders unknown" case - not nice but functional.
Afaik, FreeCol does not support GENDER, thus it might be good to point to the places where supporting GENDER would make it better.
