the hardest thing to fight for and the easiest thing to lose.

means A calm, untroubled state of mind or surroundings, free from conflict, anxiety, or disturbance.

from Built from "peace," which came into English through Old French "pais" from Latin "pax" (peace, also the root of "pact" — peace as something agreed upon), plus the native English suffix "-ful" (full of) and "-ness" (the state of being). So the word literally layers up to "the state of being full of peace," a Latin core wrapped in two homegrown English garments.
