What is the word with the most definitions????

It is not what.

Here is something a friend emailed me that I wanted to share;

An amazing 2 letter English word.

 A reminder that one word in the English language that can be a noun, verb, adjective, adverb and preposition.  

UP 

  Read until the end .....  you'll laugh. 
 
  This two-letter word  in English has more meanings than any other  two-letter word, and that word is 'UP.'  It is listed in  the dictionary as an [adv], [prep], [adj], [n]  or [v]. 
 
It's easy to  understand UP, meaning toward the sky  or at the top of the list, but when we awaken in  the morning, why do we wake UP? 
 
At a meeting, why  does a topic come UP?  Why do we speak UP, and why are the  officers UPfor election and why is  it UP to  the secretary to write UP a  report?  We call UP our friends, brighten  UP a room, polish UP  the silver, warmUP the leftovers and clean  UP the kitchen.  We  lock UP the house and fix  UP the old  car 
  
At other times, this  little word has really special meaning.   People stir UP trouble, line  UP for tickets, work  UP an appetite, and think UPexcuses. 

To be dressed is one  thing but to be dressedUP  is special. 
 
And this  UP is confusing:  A  drain must be opened UP because it is stopped  UP.

We open  UP a store in the morning  but we close it UP at night.  We seem  to be pretty mixed UP about UP!
 
To be knowledgeable about the proper uses of UP, look UP the word UP in the dictionary.   In a desk-sized dictionary, it takes  UP almost  1/4 of the page and can add UP to about thirty  definitions. 
 

If you are UP to it,  you might try building UP a list of the many ways  UP is  used.  It will take UP a lot of your time, but  if you don't give UP, you may wind  UP with a hundred or  more. 

When it threatens to  rain, we say it is cloudingUP.  When the sun  comes out, we say it is clearing UP.  When it rains,  the earth soaks itUP.  When it  does not rain for awhile, things dry UP.  One could go on  and on, but I'll wrap it UP, for now . . . my time  is UP! 
 
Oh . . one more  thing:  What is the first thing you do in  the morning and the last thing you do at  night? 

U 
  
  P
 
Did that one crack  you UP? 
 
Don't screw UP  Send this on to  everyone you look UP in your address book   . . or not . . . it'sUP to you. 
 
OK..OK...Now I'll shut UP!

Excellent

That's because English is not your first language, no offense indended.....English is a non sequitur language with an incredible amount of idiosyncrasies, contradictions, and paradoxes that make it hilarious.
