barbarous

Sense: adjective/1
Cruel is the most general word of this group — it describes any deliberate infliction of pain without the historical or cultural overtones of barbarous. Savage overlaps closely with barbarous in both cruelty and primitiveness, but savage is more emotionally charged and common in everyday speech. Brutal focuses on physical harshness and violence (brutal force, brutal winter) and lacks the 'uncultured' dimension entirely. Uncivilised is the mildest of the four — it describes a lack of polite refinement rather than active cruelty. For example, eating with your hands may be called uncivilised but not brutal; a mass murder is brutal or savage but calling it uncivilised would sound too weak.

Etymology
From Latin barbarus ('foreign, uncivilised'), borrowed from Ancient Greek βάρβαρος (barbaros, 'foreign, ignorant'). The Greeks used the word to describe anyone who did not speak Greek, imitating the sound of foreign languages as 'bar-bar' — speech that sounded like meaningless noise. This sense of 'foreign' gradually shifted toward 'uncivilised' and then 'cruel'.
