Judging by some of the posts on meta1 and comments posted there it seems that there are users who try to improve the posts by correcting spelling mistakes. Of course, there are other ways to improve the posts via editing, some of them probably more important than grammar and spelling. Still this is certainly an improvement, a post with correct spelling is easier to read and using English correctly also increases the professional appearance of this site. Moreover, it helps with searching. (Posts which contain only the misspelled form of the words are less likely to be found when searching.)
Maybe it could be useful to collect some commonly misspelled words. This could make it easier for users, who have some spare time and want to do a few such edits, to find posts which have this problem.
For this reason it might be useful also include link to a search (or a SEDE query) which returns those posts. Some minor comments on searching:
- For some words, the search also returns posts which contain minor variants of the words. Since we are searching for misspellings, in such cases adding quotation marks might help to find the misspelled ones. (For example, searching for occurence returns many results, but we are more interested in the ones which are found when we search for "occurence" and "occurences".)
- A simple SEDE query searching for some string can return words which contain this string as a some part. So sometimes we might want to look only at results containing exactly the given word. (Compare the results searching for teh with the results where teh is preceded and followed by a non-letter).
- It is better to use case insensitive version of SEDE queries. (So that we catch also misspelled word at the beginning of a sentence. This is especially important for names.)
- With SEDE you can find several words which contain the same substring. For example, words containing "anali" might often be typos (such as analisis, analise, analitic, etc.} and you can search for anali.
A few comments about editing the misspellings. (Some of them apply to editing in general.)
- It is better to avoid bumping too many old posts at the same time. (Frontpage is considered a precious commodity.)
- For this reason it is better to concentrate on questions which are new or have been recently bumped for some other reason.
- If you edit some post, try to check whether there are also other improvements to do. (Since the post was bumped by correcting the misspelled word, it is better to improve also other things which are worth editing than to bump the same post by additional edits later.)
- Difference between British/American spelling should not be considered a misspelling, as discussed before: Is English (US) vs English (UK) grounds for an edit?
Some names of mathematicians which are commonly misspelled can also be found in this answer: Searching for accented characters is too strict. (Although that answer is primarily about alternative spellings.) This might also help when creating list of common misspellings.
1Posts such as: Edit session for wrong spelling of mathematicians and mathematical concepts or Wrong spelling of “occurrence”. Some users have mentioned in chat that they do this kind of edits, for example, Srivatsan.
2These SEDE queries are more for people who are curious (since they do not actually help with editing), but they still might be interesting anyway. You can find posts where a specific word has already been corrected. You can also search in comments for some string or for an exact word.
