Wag the dog

Wait for a raindrop in the drought

Waiting in the wings

Wake up and smell the coffee

Wake-up call

Walk a fine line

Walk a mile in my shoes

Walk a tightrope

Walk in the park

Walk on eggshells

Walk Spanish

Walk the green mile

Walk the plank

Walking encyclopedia

Walking on air

Walking on broken glass

Walking time-bomb

Wallflower

Walter Mitty

War chest

War of words

Warm and fuzzy

Warm the cockles of your heart

Warpath,

Warts and all

Wash your hands of something

Waste not, want not

Waste of skin

Watch grass grow

Watch your back

Watch your six

Watching paint dry

Water off a duck’s back

Water over the dam

Water under the bridge

Water, water everywhere, nor any drop to drink

Watering hole

Watery grave

Way to go

Weak at the knees

Wear many hats

Wear sackcloth and ashes

Wear the trousers

Wear your heart on your sleeve

Weasel words

Weather a storm

Wedge politics

Wee buns

Wee hours

Weight off your shoulders

Well-heeled

Well-oiled

Well-oiled machine

Were you born in a barn?

Wet behind the ears

Wet blanket

Wet your whistle

Whale of a time

What can sorry do?

What can you expect from a hog but a grunt?

What does that have to do with the price of tea in China?

What goes around comes around

What will be will be

What’s cooking?

What’s good for the goose is good for the gander

What’s the damage?

What’s up?

What’s your poison?

What’s your take on that?

Whatever floats your boat

Wheels fall off

Wheels within wheels

When hell freezes over

When in Rome, do as the Romans do

When it rains, it pours

When pigs fly

When the chickens come home to roost

When the dust clears

Where the rubber meets the road

Where there’s a will, there’s a way

Where there’s muck, there’s brass

Where there’s smoke, there’s fire

Whet your appetite

Which came first the chicken or the egg?

While the cat’s away, the mouse will play

Whistle down the wind

Whistle for it

Whistle-stop tour

Whistling Dixie

Whistling in the dark

Whistling past the graveyard

White as a sheet

White as snow

White elephant

White feather

White lie

White-bread

Who has eaten of the pot knows the taste of the broth

Who wears the pants?

Who will ring the bell?

Whole ball of wax

Whole cloth

Whole kit and caboodle

Whole new ball game

Whole nine yards

Whole shebang

Why buy the cow when you can get the milk for free

Why keep a dog and bark yourself?

Wide berth

Wide of the mark

Wild goose chase

Wildcat

Wilder than a peach orchard boar

Will never fly

Will-o’-the-wisp

Win by a nose

Window dressing

Window to the soul

Wing and a prayer

Winner takes all

Wipe the floor with

Wipe the smile of someone’s face

With a heavy hand

With child

With flying colours (colors)

With friends like that, who needs enemies?

Wither on the vine

Within a whisker

Without a hitch

Woe betide you

Woe is me

Wolf in sheep’s clothing

Wood for the trees

Word of mouth

Word of the law

Words fail me

Work like a charm

Work like a dog

Work the system

Work your fingers to the bone

Work your socks off

Work your tail off

World at your feet

World is your oyster

Worm information

Worm turns

Worm’s eye view

Worse for wear

Worse things happen at sea

Worth a shot

Worth its weight in gold

Worth your salt

Wouldn’t pull the skin off a rice pudding

Wouldn’t touch it with a bargepole

Wouldn’t touch it with a ten-foot pole

Wrap yourself in the flag

Wrench in the works

Writ large

Write your own ticket

Writing on the wall

Written all over your face

Written in stone

Wrong end of the stick

Wrong foot
