Not inclined to engage in war or conflict; peaceful in nature.
The unwarlike nation focused on diplomacy rather than military action.
Unwarlike → It is formed from "un-" (meaning not) and "warlike" (from Old English "werlic", meaning of or pertaining to war). The word "unwarlike" means not inclined to engage in war or conflict.
Think of 'not' ('un-') being added to 'warlike', which describes someone who is not inclined to war or conflict.
