The Shortest Sentence In the World

What is the shortest sentence in the English language?

Jelly donuts (ice cream is better)

The typical answer to this is “I am,” but some argue that it’s not a complete sentence. However, if someone asked a man named Rupert if he was Rupert, he could reply, “I am” and it would make a complete sentence in my book.

But that’s not the whole answer. There is an even shorter sentence using an imperative with an implied subject (how’s that for an English terminology-filled sentence?) With “Go,” the “you” is implied. For example, if your wife wanted you to go with her to pick up some donuts and you were busy, she might say, “I really want to get some donuts, I’m starving!” and you might reply, “Go!” The implication being you never wanted to get donuts in the first place because you like ice cream more anyway and if you’re busy you’re probably doing something worthwhile and important and can’t be disturbed for such trivial matters as acquiring sweet pastries with holes in them, no matter how much of a waste of time your wife says your pursuits are. In short, “Go” is the shortest sentence in the English language that also has the longest implied meaning. Do you want to get get some ice cream? Go!

Ava pointed out in the comments that No is another viable alternative.

Two Halves And a Whole

Complete the three missing words in the sentence, with the first two words combining to form the third word.

For example:

The prime minister ____ the meeting, even though the ____ was technically the ____ official.
The three missing words would be RAN, KING, and RANKING.

Now solve this one:

When she broke her ____ showing off at the ____ of the ski run, Arya became a ____ among her friends.

LEG, END, LEGEND

When she broke her LEG showing off at the END of the ski run, Arya became a LEGEND among her friends.

I Lack Much Reason, But Often Rhyme

I lack much reason, but often rhyme,
And require logic to pass the time,
To get the words to tell your kin,
Look for clues that lie within,
Though all are different, they act the same,
The answer is practically in the name.

What am I?

A riddle.
