Might as well throw in the trowel.
Dear Word Detective: I have been having an ongoing argument with a dear friend about the phrase “for all intents and purposes,” which she swears to the death is “for all intensive purposes,” and says I sound like a ninny when I say it wrong. Can you figure out how this phrase crept into common usage and help us settle this dispute? — Collectively Confused in Columbus.
I guess this column isn’t as effective a deterrent to silliness as I had hoped, because I actually answered a question about “to all intensive purposes” about ten years ago, and yet here we are again. You are, of course, correct, and not at all a ninny, at least on this question. The phrase is indeed “for all intents and purposes,” meaning “for all practical purposes” or “in any reasonably likely circumstance” (“After Bob punched his boss, his career at the firm was, for all intents and purposes, kaput”). “For all intents and purposes” has been around since at least 1546 (in the form “to all intents, constructions, and purposes” contained in a law decreed that year by Henry VIII).
The mangled form “for all intensive purposes” has been “spotted in the wild” in print (and noted by linguists) at least since the 1980s, although, as an error in speech, it may have been around much longer. “For all intensive purposes” is a classic “eggcorn,” a re-shaping of a word or phrase that, far from being a simple error, has flourished and persisted because it actually makes a certain amount of sense. The term “eggcorn” itself was coined in 2003 by linguist Geoffrey Pullum when someone online was noticed typing “eggcorn” instead of “acorn.” It was, of course, an error, but an acorn is indeed rather egg-shaped, and is a seed, as is corn, so if one has heard “acorn,” but never seen the word in print, writing it as “eggcorn” is not entirely crazy.
Similarly, “for all intensive purposes” might be defended as logical if “intensive” were interpreted to mean “serious, realistic, or practical,” making the phrase equivalent to “when push comes to shove” (“Smith is a decent hitter, but for all intensive purposes, he’ll be useless in the playoffs”). It’s still “wrong” in that it mangles a long-established English idiom, but it’s not as far off the beam as “The ants are my friends, they’re blowin’ in the wind” or “There’s a bathroom on the right.”
As to how “intensive purposes” crept into common usage, I think it’s significant that the 1980s also saw the proliferation of “intensive care units” in hospitals and the ensuing use of “intensive” to sell everything from skin lotion to motor oil. Given that “intents and purposes” has a distinctly archaic ring to it, and that “intents” is more rarely used than “aims” or “goals” today, and “intensive” seems like a logical interpretation to folks who have only heard (and never read) the proper form of the phrase.


a student once wrote: it’s a doggy dog world.
ranks right up there with “for all intensive purposes”!
See the above link, Stan. Perhaps your student performed an allusion more complex than you realize.. ;)
One of my favorits was written by a WAC who was asked on a questionnaire to comment on the food at the base where she was stationed: “The food in the mess hall is alright, but some of it is left to be desired.”
Interesting. My ex-wife thought it was a “doggy-dog” world (N of Pittsburg, c1970) and I, in my younger days (1960s, Georgia)) thought, for all intents and purposes, it was “for all intensive purposes.”
I thought it was “for all intent and purpose” in other words what it was intended for and for it’s purpose… ??
Ouch. Not only the incorrect “for all intents and purposes”, but also the wrong form of “its”. Another thorn in the side of any English teacher. “It’s” is short for “it is”. The possessive form of “it” is “its” with NO apostrophe. So, here you should use “and for its purpose…??”
@Wanda Mahoney:
The word “all” is the main clue. The English language won’t permit “all intent” any more than “all person”.
We repeat what we think we hear, just as someone once thought he heard “I could care less”, because the “couldn’t” wasn’t clearly spoken.
Obviously, if we care not at all, we are at the bottom of the caring pole, so we cannot care less.
My English teacher told me that “I couldn’t care less” was incorrect because it is a double negative, the ‘not’ and ‘less’, and although the phrase “I could care less” doesn’t literally mean what one thinks one is saying it is still the correct version of the phrase.
You’re English teacher wuzn’t not wrong.
And a “Doggy Dog World” is only acceptable if you are quoting Snoop-Dog.
