A state of peace and calm where there is no stress, noise, or disturbance.
From Latin 'tranquillus' meaning calm or peaceful. Entered English in the 1400s through French. The double-l spelling is the British preference, though 'tranquility' (single-l) is common in American English.
Tranquillity is so rare in modern life that it's become almost luxurious—spas and meditation apps literally sell the promise of recreating this ancient Roman ideal of inner peace that people valued 2,000 years ago.
