You have to use two words that are each their own opposite (auto-antonyms, contronyms, contranyms or whatever you want to call it) in the same sentence. This means that each of the two words in used twice, and for each word, the two occurrences have meanings that are opposite (contradictory) (**or extremely different ** meaning they are so different one could argue they're opposites.) to each other. This sentence must be a grammatically correct English sentence.

It's ok to use minor variations on words such as plurals or conjugated verb forms.

The goal is to make it short (in terms of characters). The accepted answer will always be the shortest. To save me trouble, it'd be nice for you to post the number of characters in your sentence. Spaces and punctuation count; you can use this site to check.

Anti-loophole: the words you choose must each be used twice, once as one meaning and again as another.

    $\begingroup$ By "opposite" do you just mean "different"? None of the current answers seem to me to have words that are opposite meanings. $\endgroup$ – starsplusplus Dec 19 '14 at 10:43
  • $\begingroup$ @Sp3000 I already followed the link in one of the answers; the explanation seemed to imply simply different rather than opposite, but I thought I'd post here to check first. $\endgroup$ – starsplusplus Dec 19 '14 at 11:14

    $\begingroup$ I downvoted because the answers being accepted use words that are nowhere near opposites. I understand that there's inherent ambiguity in any such challenge, but this is just unreasonable. $\endgroup$ – xnor Dec 20 '14 at 6:04

Using an archaic form of 'let', this ties with the currently first place answer:

Let be or be let.

  • Let: To allow OR to hinder (archaic).
  • Be: The way something already is OR to become different.

Translation: Allow things to stay as they are, or you will become hindered.

Arguably, we can shorten this by removing the 'or' (which flips the meaning of the sentence) and using an implied conditional:

15 Characters

Let be; be let.

Translation: If you allow things to stay as they are, then you will become hindered.

  • $\begingroup$ You can trim this by one character by eliminating the semicolon - It would be the same as saying "Allow the word be to be hindered." $\endgroup$ – corsiKa Dec 20 '14 at 19:09

    $\begingroup$ True, but then I think the word 'be' would lose the contranym-ness of the current sentence (staying in an existing state vs. changing to a new future state). I do wonder, though, whether it would be grammatically acceptable to replace the semicolon+space with a single (unspaced) em-dash. $\endgroup$ – Caleb Hines Dec 20 '14 at 19:17

Bolt me fast, or bolt fast.

We have:

  • bolt: secure in place, or dash away suddenly
  • fast: firmly fixed, or quickly

The intended meaning is "Either tie me down securely or run away quickly". As @xnor remarks: "I guess the speaker is a werewolf" (thanks for helping!).

If the above sentence wasn't ambiguous enough for you, we can take out the "me", leaving it implied. This has the hilarious consequence:

Bolt fast, or bolt fast.

Same meaning as above, but body language/intonation are necessary for this one to work. It helps if you imagine a movie scene between a male werewolf and a young girl reluctant to tie him up on a full moon.

  • $\begingroup$ Your first use of fast can be an adverb (which I think is more common than as an adjective), which saves chars as "Bolt him fast". $\endgroup$ – xnor Dec 19 '14 at 5:05
  • $\begingroup$ @COTO You're missing the "held in place" part. I'll try to come up with a more adequate explanation, but it's no different to how it's presented on auto-antonym lists (I just wrote "tightly" as a word to mentally replace "fast" with in the sentence, not implying that's all it means) $\endgroup$ – Sp3000 Dec 21 '14 at 1:08

The custom is to turn off custom alarms that go off.

The first "custom" means "standard", the second means "tailored". The first "off" means "disable", the second off means "engaged".

One bar bars one.

  • The first one is a single instance of something
  • The first bar is a place where you are served drinks
  • The second bar means to prohibit someone from being served
  • The second one is the general third person pronoun, referring to all people in general

You could imagine a context something like this:

One bar bars one, and suddenly one gets a reputation for being a troublemaker!

If you don't like the fact that the second bar has an s on the end (several other answers have "modified" forms like this, but I'm a bit of a perfectionist...), you could have

One bar did bar one.

which has an extra 4 characters, bringing the total to 21.

I couldn't help but help, so I left the pies that were left.

The first "help" means "resist;" the second "help" means "assist."

The first "left" means "went away;" the second "left" means "remaining."

If articles are required, then 24 characters:

A tipped cop cops a tip.

"A local police officer, recently in the news for having been knocked over on his beat by a fleeing pickpocket, has been caught with his own hand in the proverbial cookie jar, stealing the end of a ceremonial flagstaff at headquarters."

Resign old, resign when old

33 Characters

Resign to resign old job when old

First resign means 'to quit'. Second resign means 'signing up again'.

First old means 'past'. The second old means 'later state'.

Note: Not the shortest, but shorter than some other answers.

Originally I was puzzled by this question, but I soon puzzled it out and came up with:

At first I held fast as my alarm went off, but soon I had to turn it off, for morning was fast approaching.

That probably won't win the shortness award, but it's an example of fairly standard auto-antonyms. I could probably shorten it by removing/changing some words while still being grammatically correct, but it wouldn't sound very good to my ear.

Left's right, right's left

Not exactly opposites, but in context:

The answer to the left question is right, the right question is left.

  • $\begingroup$ I'm struggling to make the contrast of tenses in the first example make sense. It feels like it should either be fixed left, left fix or fix left, leave fix in order to be grammatically correct? $\endgroup$ – starsplusplus Dec 19 '14 at 16:37

Fix the rules, don't fix the rules. (35)

Fix (as in: for the love of English, stop changing) the rules (a set of immutable guidelines), don't fix (incessantly edit in vain attempts to repair) the rules (an ever-changing and unenforced bunch of suggestions that apparently no one is taking seriously).

That's all I got.

Riot left, left a riot

Riot 1: Violent disorder

Left 1: Going away

Left 2: Staying

Riot 2: Lots of fun


~ 44 characters ~

Obviously not short, but I think it's kind of cute:

Fine, I can't help it - I'll help you, fine gal!

Fine as in: acceptable, just barely satisfactory / exceptional, very nice

Help as in: prevent, stop / the 'normal' help


Infamous depressed depressed Infamous 35 characters.

I think that infamous can mean both well known or not popular. Depressed means sad or a button pressed in for a positive response.

So a famous person who is depressed presses the depressed button that says Infamous on it.

This has a lot of letters, but maybe it can lead us to other shorter words that can have opposite meanings.

  • $\begingroup$ I like the "X depressed depressed X" structure, though I'm not sure the second infamous works so well. $\endgroup$ – starsplusplus Dec 20 '14 at 14:31

Worn - used up retired - stopped working retired - did work to change a tire Worn - in use as clothing
