She is much bossier than her brother, always telling him what to do.
Bossier is derived from the French word 'boss' (meaning a person in charge or a leader) and the suffix '-ier' (meaning one who). The word 'bossier' refers to someone who is more bossy or domineering than others.
Think of someone who is 'in charge' ('boss') and the '-ier' means a person. So, a 'bossier' person is someone who is more like a boss.
