If I were a rival king in the middle ages, would I use "koninkje" to demean an boy king?
For example, let's say I meet this fellow at a meeting before a battle. This boy king has called for peace, but I'm not interested in peace. I want to conquer his lands and make him my one of my many subjects. Would refering to him as "koninkje" help me start a war? This is going to be immediately relevant in my day to day life, and so I must know!
