serene - calm
To be ‘serene’ means to be quiet and untroubled. It was originally used in a literal sense to refer to calm and clear weather conditions, but has since been adapted to more commonly express a person’s relaxed demeanour. The word implies a level of tranquilness that can be considered to be idyllic and is therefore always used in a positive sense.
