A Study of Some of the Most Commonly Misspelled Words

I made a search of posts to Internet (Usenet) newsgroups using
Deja News < http://www.dejanews.com/ > coming up with a count of how many times a word was spelled with the conventional spelling and comparing this with how often it was spelled with an alternative form, or "misspelled." (This was inspired by a discussion in the newsgroup "alt.usage.english" in which a similar, but smaller, study of a few misspelled forms was done using a search engine.) Spellings other than the standard form were used more than 33% of the time for these words in posts to Usenet discussion groups:
minuscule 68% of the time spelled otherwise
millennium57
embarrassment55 (embarrassing 35%)
occurrence44 (occurring 37)
accommodate40 (accommodation 39)
perseverance36
supersede 35-50 (superseded 44)
noticeable35
harass34
inoculate34

Next are words that were misspelled between about 20% and 33% of the time in posts to the newsgroups:
mischievous 32%
pastime 24%
occurred 31
separate 23 (inseparable 21%)
embarrass 30 (embarrassed 29)
preceding 22 (preceded 21)
indispensable 29
definitely 20
privilege 28
gauge 20 (gauges 25)
questionnaire 28

And these were misspelled between 10% and 19% of the time:
existence 18% miniature 14%
publicly18 precede 13 (precedes 11%)
weird 17 rhythm 12
separately 17 (separated 16%) conscientious 11 (conscious 10)
misspell 16 hierarchy 11
grammar 15 calendar 10
withhold 15

Anecdotal evidence and personal observation indicate that a few other cases where a "non-standard" spelling is frequently used on the Internet are _alright_ for _all right_, _alot_ for _a lot_, and _it's_ for the possessive _its_. However, search engines don't look for extremely common words (asking one to search for posts with the word _the_ would turn up just about every post ever made) and looking for two-word phrases (_all right, a lot_) is trickier than for a single word. Too, to determine the rate for the possessive _its,_ one must look thru each individual post to determine whether _it's_ was used incorrectly for the possessive _its_ or whether _it's_ was used correctly for the contractions _it is/it has_. So, I didn't search for these three cases, but it may well be that _all right, a lot_, and the possessive _its_ are among the most frequently misspelled words in Internet postings.

A few other words to note, with misspelling rates below 10% in items posted to Usenet discussion groups: commitment, conceding, occasionally, seize 9%; conceded, paralleled, sovereign 8%; repetition 7%; commission, concede, counterfeit, forfeit, maintenance 6%; concedes, height, receive, threshold 5%; committee, deceive, forty, immediately, proceed 4%; conscience, foreign, parallel, proceeds, sincerely 3%; government 2%; business, necessary 1%.

Notes about _minuscule_, _gauge,_ and _misspell_.... For these words there are also dictionary-given alternative spellings. _Minuscule_ has been "misspelled" as _miniscule_ so many times in so many places that _miniscule_ is now a valid variant in some dictionaries, > as you can read in this linkas you can read in this link. Now since _miniscule_ is given as a variant spelling in dictionaries, it could be said that technically one isn't "misspelling" _minuscule_ by writing _miniscule_. However, the purpose of the study here is to see how many people spell a word in a way other than the (one) accepted standard -- thus the distinction is between "standard" spellings on one hand versus anything else.

With _gauge_, the dictionary-accepted variant is _gage_, and the situation is different from that of _miniscule_. In certain fields (science, engineering), _gage_ is the more commonly used, that is "standard," spelling. In the figures above, I have simply not counted _gage_ one way or the other (by using the criteria I mentioned in the previous paragraph, _gage_ would be in with the "other than standard forms. Thus, by Deja News, I had 8879 hits for _gauge_ and 2211 for _guage_. I computed the position above from those two: 2211 / (8879+2211) --> 20%. (I also got 1848 hits for _gage_.)

For _misspell/misspelling_, some use the hyphenated forms _mis-spell_ etc. instead. Further, _misspelled_ is common in the U.S., while _misspelt/mis-spelt_ is the usual form in most other English-speaking countries. I didn't count the hyphenated forms of _mis-spell_ one way or the other. I found 486 instances of _misspell_, 52 for _mis-spell_, and 87 for _mispell_. Cases of _misspelled_ total 2254; _mis-spelled_ 209; _mispelled_ 452. For _misspelt_, 148; _mis-spelt_ 70; _mispelt_ 32.

Note about _supersede_... There is Asymetrix's "SuperCede for Java." Some of the posts I found in searching for _supercede_ were indeed about Asymetrix's SuperCede. (It's not case sensitive, so _supercede, Supercede, SuperCede_, etc. all turn up). I searched for occurrences of _supersede, supercede, superceed_, and _superseed_. The form _supersede_ made up about 45% of the total. There were just a few hits for _superceed_ or _superseed_, while almost all the rest -- almost 55% -- were _supercede_. From reading thru many of the posts, I determined that at least two-thirds of the time _supercede_ was being used for the word _supersede_, while one-third or less it was for Asymetrix's SuperCede.

Notes about _mischievous_ and _height_... With each of these words, some of the non-standard spellings I found also reflect widespread non-standard pronunciations each of these words have. _Mischievous_ is often (erroneously) pronounced as if there were an "i" (or "e") between the "v" and the "ous." The spellings and number of occurrences found in this survey:

      mischievous  1203    mischevious   255    mischeivous  51
			   mischievious  182	mischevous   15
			   mischeivious   30    mischivous    8
			   mischieveous    7
			   mischiveous     7
			   mischeiveous    2

_Height_ is sometimes pronounced as if the final "t" were "th" as in _think_. However, only some of the misspellings of _height_ were those ending in "-th"; and the most common non-standard spellings of _height_ were _hight_ and _hieght_. _Hight_, incidentally, is given as a valid variant of _height_ in some unabridged dictionaries.

Here are the numbers of individual spellings found for some of the other words in this study:

=================================================

Before doing the study of Internet newsgroups, I surveyed published lists of frequently misspelled words. The scope of the lists was American English (I live in the U.S. and used what material I could find), and the study covered nine lists which I found in books. I have recently added into that study two lists from British sources, a total now of eleven lists. The words found most often on those lists:

On ten of the eleven lists of commonly misspelled words:
		    accommodate
		    embarrass
		    grammar
		    forty
		    separate

On nine of the lists: business harass necessary parallel privilege

And on eight of the eleven: all right existence occurrence calendar government perseverance commitment height rhythm committee immediately seize conscientious indispensable transferred description maintenance

(For the pool of words I used in the study of Usenet postings, I used those listed here which appeared in the majority of the published lists of commonly misspelled words, and added to that other words that were high-ranking on those lists or which had been mentioned as "candidates" by others.)

Below I have a sort of "combined results," and of course there are a number of ways that one could show combined results for this. I have taken the words which appeared on nine or more of the eleven published lists; I have taken the words which were misspelled 20% or more of the time in my study of posts to Usenet discussion groups; and I have combined them, into the following chart. This then has those words that appeared on at least nine of the published lists *and* were misspelled 20%-plus of the time on the Usenet discussion groups; it also has those which appeared on at least nine of the lists, but which were misspelled *less* than 20% of the time on Usenet; and it has those which were misspelled 20%-plus of the time on Usenet, but which appeared on *fewer* than nine of the published lists:

	   Misspelled   On N of		       Misspelled   On N of
	    Approx N%	the 11			Approx N%    the 11

(A final note: Many search engines, such as Deja News, now allow one to search items from just a particular language, so this could be conducted in other languages for comparison.)
