Near is my kirtle, but nearer is my smock
Necessity is the mother of invention
Neither a borrower nor a lender be
Never ask pardon before you are accused
Never buy a pig in a poke
Never do things by halves
Never judge by appearance
Never look a gift horse in the mouth
Never put off till tomorrow what you can do today
Never say die
Never tell your enemy that your foot aches
Never trouble trouble till trouble troubles you
Never underestimate your opponent
New broom sweeps clean
New lords, new laws
No answer is also an answer
No man is indispensable
No man is an island
No man is infallible
None but the brave deserve the fair
No news is good news
No smoke without fire
Nothing comes of nothing
Nothing succeeds like success
Nothing ventured, nothing gained
