[Retric]

Reducing things to exclusively Germanic/Scandinavian roots without any crossing to old French etc would massively restrict vocabulary so yes you could hold a conversation but you could also hold one without any of those words. Both could seem natural or really stilted depending on the subject and your approach to dialogue.

When you say fancy it’s not just allure or autocrat, but also words like age, air, alarm, aunt, chair, money, beef, dance, etc
