Under white ashes lie often glowing embers.

Unwilling service earns no thanks.

Unworthy offspring brag the most of their worthy descent.

Vice is learnt without a schoolmaster.

Vice is most dangerous when it puts on the garb of virtue.

Vipers breed vipers.

Virtue in the middle, said the Devil, when seated between two lawyers.

Want and necessity break faith and oaths.

Want of variety leads to satiety.

Wanton kittens make sober cats.

We are all well placed, said the cat, when she was seated on the bacon.

We must bear our cross with patience, said the man when he took his wife on his back.

We must eat a peck of dirt before we die.

We must sow even after a bad harvest.

We must suffer much, or die young.

Weeds never die out.

Weighty work must be done with few words.

Welcome is the best cheer.

What is got by begging is dearly bought.

What is gotten over the devil's back is spent under his belly.

What is play to the cat is death to the mouse.

What is play to the strong is death to the weak.

What is sweet in the mouth is not always good in the stomach.

What you do yourself is well done.

What you learn to your cost you remember long.
