tranquil

Tranquil is an adjective that describes conditions or states free from disturbance or turmoil, conveying quiet, calm, and serenity. It can refer to landscapes and environments, such as a tranquil lake or a tranquil garden, as well as to inner states of mind, such as a tranquil mood or a tranquil temperament. The term often implies a sustained, undisturbed stillness rather than a temporary pause.

Tranquil comes from Latin tranquillus, meaning calm or quiet, via Old French tranquille, entering English in the late medieval period. It generally conveys a sense of steady, undisturbed calm rather than a brief lack of noise.

Tranquil is commonly used in descriptive writing to evoke serenity; it can contrast with words like tumultuous, noisy, or chaotic. The noun form is tranquility; the related verb is tranquilize (to calm or sedate), and the noun tranquilizer refers to a drug or agent that produces calming effects. In geography or travel writing, you might encounter phrases such as a tranquil coast or a tranquil retreat.
