gladek krotek miren nemoten spokojen tih
(of a body of water) free from disturbance by heavy waves
a ribbon of sand between the angry sea and the placid bay the quiet waters of a lagoon a lake of tranquil blue water reflecting a tranquil blue sky a smooth channel crossing scarcely a ripple on the still water unruffled water
