I work in a lab that uses dewars constantly. A dewar is a light-tight, vacuum- and temperature-controlled container for doing sensitive scientific testing.

Now, dewar is not in the standard Word dictionary, so I added it the first time I saw the red squiggly line (spelling) under it. However, now it is replaced with a green squiggly line (grammar), and Word suggests that every instance of "dewar" should be "Dewar." It's not a proper noun, and I don't know how it got that idea.

I thought I may have added the capitalized version to the dictionary by coincidence (maybe it started a sentence). So, I went under the "File" tab, selected "Options", and then selected "Proofing" in the pop-up window. Then I clicked on the "Custom Dictionaries" button. I clicked on the "Edit Word List..." button in the pop-up window and found "dewar" and "dewars" in the list and deleted them.



I then went back to a working document, and found the familiar red squiggly line under "dewar" for spelling. This time I am sure it was lower case. When I right-clicked on the word, Word suggested "Dewar" as the correct spelling. I clicked on "Add to Dictionary" instead, but then the green squiggly line was still there. I right-clicked again, and Word was still insisting that it should be "Dewar".

Other words that I've added to the dictionary don't seem to have this uppercase/lowercase problem.

Please help! It's very annoying to constantly tell Word to ignore that particular instance of "grammar" every time the word comes up in 30+ page documents.

So, a quick Google search of "dewar" tells me that someone famous is named Dewar, along with Dewar's Whiskey, and there is a certain type of flask called a "Dewar flask" (capitalized).

I think I should still be able to tell Word that I don't want it capitalized, though, right?

For reference, it is not common in non-chemistry communities to capitalize "dewar." here is a NASA web page that has it in lower case (see the caption under the picture):

If you right-click on dewar and dewars in your document when it has a green underline, you can tell Word to Ignore the rule. I do not know what effect this will have on your other writing. It does get rid of the green underline, though.

I have tested and it remains gone through a Word restart.

Most of what I know about the spelling/grammar checker, I learned from Mastering the Spelling Checker.

Well, I'd like for Word to find other words that should be capitalized, but aren't (like Monday). Ignoring the rule gets rid of an important part of the spell check.

I'm looking for a way to exclude just the word from the grammar check, like I can exclude the word from the spell check.
