What is ms word/definition i want to know please

MS Word is a desktop publishing software , part of a suite of
applications called Microsoft Office.

MS Word is dedicated to
document writing, as opposed to spreadsheets or graphic drawing.

Unless
you are not actually wanting a definition on what MS Word is, and you
are actually inquiring on 'definitions' in Word, well that is talked
about under Defining Styles in Word.

you can configure this in
Word 2003 by following these steps:

On the Tools menu, click AutoCorrect
Options, and then click the AutoFormat As You Type tab.


Under Automatically as you type, select or clear the Define styles based on your formatting check box.
