a lake of tranquil blue water reflecting a tranquil blue sky.
a legato passage.
a long, smooth stride.
a ribbon of sand between the angry sea and the placid bay.
a smooth channel crossing.
a smooth ride.
a smooth road.
a smooth tabletop.
he gave his hair a quick smooth.

polish my shoes.
scarcely a ripple on the still water.
shine the silver, please.
smooth fabric.
smooth skin.
smooth the surface of the wood.
smooth the way towards peace negotiations.
the bill's path through the legislature was smooth and orderly.
the fluid motion of a cat.
the liquid grace of a ballerina.
the manager pacified the customer with a smooth apology for the error.
the quiet waters of a lagoon.
unruffled water.
water as smooth as a mirror.
