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.
Mike, Jimmy, Nader, Kevin, and Larry were the top five finishers in the regional 500-mile race. They drove yellow, orange, green, red and blue cars but not necessarily in that order.
Neither Kevin nor Larry drove the green car.
Kevin finished faster than Mike and Larry.
The blue car finished earlier than Larry’s and Nader’s car.
The yellow car finished faster than the green car and the orange car.
Mike’s and Larry’s car finished ahead of the orange car.
Jimmy’s car finished before the blue and the yellow car.
Who drove what color car and what place did each driver finish?
One evening a man is walking home from work and an insect flies into his ear. He tries to pry it out but it doesn’t work. Shaking his head isn’t successful either. Finally he managed to get it out. How did he do it?
Finley’s friends all chipped in to buy her a wedding gift. At first, ten friends agreed to contribute the same amount. Then two “friends” dropped out. The remaining eight had to add another dollar each to cover the cost of the gift. How much did the gift cost?
From a basket of mangoes when counted in twos there was one extra,
counted in threes there were two extra,
counted in fours there were three extra,
counted in fives there were four extra,
counted in sixes there were five extra,
but counted in sevens there were no extras.
At least how many mangoes were there in the basket?
119. The number has to be evenly divisible by seven for there to be no extras when counting in sevens, and it has to be odd in order for there to be one extra when counting by twos. It also can’t be evenly divisible by three through six. 119 is the first odd multiple of 7 that satisfies the requirements.
Someone bowled a strike. The ten white men are the pins, the dirt road is the bowling alley (it’s not dirt, but it’s the color of dirt, and if it said a smooth wooden alley it wouldn’t be much of a riddle). Three eyes as black as night are the finger holes in the bowling ball.
