Is it more correct to say a computer program is erroring out, or it is erring out? Or are both statements grammatically incorrect?

    Not a dup - the other is about errored this is about erroring Mar 15, 2015 at 11:35
  • Not a dup - the other questions are regarding technical messages in a program, this is conversational

error (third-person singular simple present errors, present participle erroring, simple past and past participle errored)

  • Note the American Heritage Dictionary (which I tend to favor as the ultimate authoritative source for US English) does not include error as a verb: ahdictionary.com/word/search.html?q=error So erring would be correct, but erroring would not, which agrees with the autocorrect on Mac OS / Firefox.

I would say that neither one is correct (from a programmer). You could say "... has an error and crashed ..." ("crashed" being the technical term for a program that suddenly stops or breaks down - except for airplane-related programs).

But that's American usage - British programmers may differ.

    I'm an American programmer and I hear "error" used as a verb all the time, often in exactly OP's construction. Oct 5, 2013 at 4:39

    As an American Software Analyst I hear, and use, "erroring out" quite frequently when discussing certain types of crashes with end users.
