Inevitable:  adjective  in·ev·i·ta·ble  \ i-ˈne-və-tə-bəl \, 

Inevitable  -incapable of being avoided or evaded

• “war was inevitable”

As I do with almost all new vocabulary words, I look for a root word within that new word, prefix or suffix. In this case i was fully aware that the “in” in inevitable meant not. I also looked at the suffix which is a word used everyday which is “able”. My definition of the word inevitable is “not able”. I researched the definition to look or the precise meaning which sums of my definition. In my own words inevitable means not able of being ignored.
