Also, it has to fill in data to complete the sentence.
If the translator returned "My person of an unknown gender, who I'm dating is earning more then I", then it would be an unusable mess.
(Yes, I know, that the word partner exists for this case, but not for every sentence and language combination)

Partner is rarely a good fit for boyfriend/girlfriend. I don't know Danish, but I wouldn't be surprised if the original term conveys a more intimate relationship than "partner". We use "partner" to denote everything from a business associate to a cowboy mate. Not exactly very specific.
