If the spell checker flags certain words as misspelled but you want it to ignore these words, you can add them to the default custom dictionary. To change the default custom dictionary where these words are added, see Change the custom dictionary to which the spelling checker adds words, below.

If you want your new custom dictionary to be the default dictionary, where any words you add will be saved, see the next task, Change the custom dictionary to which the spelling checker adds words.

When you add words while checking spelling, new words are added to the default custom dictionary, which is the one at the top of the list when you open the Custom Dictionaries dialog box. You can change the default custom dictionary used for all Office programs:

By default, when you create a new custom dictionary, the program sets the dictionary to All Languages, which means that the dictionary is used when you check the spelling of text in any language. However, you can associate a custom dictionary with a particular language so that the program uses the dictionary only when you check the spelling of text in a particular language.

The Custom Dictionaries dialog box lists the available custom dictionaries the program can use to check spelling. If the dictionary you want to use, such as one purchased from a third-party company, is installed on your computer but not listed in the Dictionary list box, you can add it.

If you want this custom dictionary to be the default dictionary, where any new words you add will be saved, see the section Change the custom dictionary to which the spelling checker adds words above.

FOLDOC was founded in 1985 by Denis Howe and was hosted by Imperial College London. In May 2015, the site was updated to state that it was "no longer supported by Imperial College Department of Computing". Howe has served as the editor-in-chief since the dictionary's inception, with visitors to the website able to make suggestions for additions or corrections to articles.[2]

The dictionary incorporates the text of other free resources, such as the Jargon File, as well as covering many other computing-related topics. Due to its availability under the GNU Free Documentation License, a copyleft license, it has in turn been incorporated in whole or part into other free content projects, such as Wikipedia.

STEM occupations have an above-average growth rate. Seven out of the ten largest STEM occupations found were computer-related, employing nearly 750,000 applications software developers, the largest STEM occupation. Learning how to create software starts with developing tech literacy, which can be done with hands-on activities in early Stem Education. Students can then attend universities like WGU to get involved in specific STEM programs like software development so they can truly be prepared for this exciting career field.

I was editing a document in Office Word 2007 on Windows XP and suddenly all sorts of words are underlined as misspelled. I go into Word options and it talks about French dictionary! In the preferences, my primary language is set to English (US) and that is only language set.

I encountered in PPT 2007 where I was typing text in and suddenly normal words, such as "your" and "windows", were being highlighted as being incorrect. I right-clicked on the misspelled words and the spelling showed what I beleive was French spelling. I looked at the main dictionary and English was selected.

As mentioned above, I also went into the REVIEW>LANGUAGE, scrolled through the list and selected English (US), even though it was already highlighted, and then clicked default. The wording that was marked as incorrect was now correct. I can only guess that I had accidently hit a key combination while typing that forced a different dictionary. ff782bc1db
