Not at war or disturbed by strife or turmoil.
"The village remained peaceful even during the distant thunderstorm, free from any signs of conflict or unrest."
In plain English: Peaceful means calm and free from fighting or arguing.
"The peaceful village was quiet and free from any noise after sunset."
Usage: Use peaceful to describe situations, places, or people that are free from conflict and disturbance rather than simply quiet. It often contrasts with active hostility but does not necessarily imply the absence of all noise.
The word peaceful comes from Middle English and is formed by adding the suffix "-ful" to "peace." Its meaning has remained consistent since it entered the language in this way.
