Manually: Select the word and go to Review | Language | Language and check the box for 'Do not check spelling or grammar.'.A more selective approach is to format the specific word as 'Do not check spelling or grammar.' Disabling proofing also disables hyphenation.If you can get away with having no hyphenation in an entire paragraph, open the Paragraph dialog, select the Line and Page Breaks tab, and check the box for 'Don't hyphenate.'.
