Cruel, vicious and completely without feeling She was imprisoned in 2015 for the brutal murder of a five-year-old boy. Not considering someone's feeling- He spoke with brutal honesty that - I was too young for the job. Vicious people intentionally hurt someone or something. Vicious is used to describe a condition that causes great physical or emotional pain- My aunt has a vicious headache. Savage means extremely violent, wild or frightening- A savage dog /beast. Very serious or cruel- A savage criticism Large and severe- Savage cuts to border force puts country at risk from terrorist...

That's a good question. The main difference here, in my opinion, would be the number of meaning each word has. Savage is usually used to describe something primitive and uncivilized, most likely referring to the violent aspect of an animal instinct. Therefore, this word can either mean uncontrollably violent or primitive and uncivilized. Brutal, on the other hand, only means violent. However, the word brutal is usually used to describe something savagely violent, describing a simple yet extreme form of violence, meaning it has a close relation in meaning to the word savage. Vicious, like savage, has many meanings to it. It can either mean "immoral" (as opposed to virtuous: vicious =/= virtuous) or intentionally and deliberately violent. (for example, a vicious murder is an intentional and violent murder) Regarding the matter whether you can use these words interchangeably or not, it would depend on which context. If used in a sentence in which the word holds the meaning "violent", then yes, I'd say the meanings of these three words (although not completely similar) are similar enough to be used interchangeably. There might be slight differences in meaning depending on the word you use, though. "He brutally/savagely (meaning it was simply yet extremely violent)/ viciously (meaning it was both intentional and violent) murdered that old lady." However, if the word you're using doesn't hold the meaning "violent", it can't be used interchangeably "Every soul on earth, virtuous or vicious, shall perish" "Native American, or more commonly known as Indian, is commonly associated with an image of a savage tribe of people" Hope this helps.
