Microsoft Word is a word processing program developed by Microsoft. It was first released on October 25, 1983, under the name Multi-Tool Word for Xenix systems. Subsequent versions were later written for several other platforms including IBM PCs running DOS, Apple Macintosh running the Classic Mac OS, AT&T UNIX PC, Atari ST, OS/2, Microsoft Windows, SCO Unix, macOS, Web browsers, iOS, and Android. Unlike most MS-DOS programs at the time, Microsoft Word was designed to be used with a mouse. It is a component of the Microsoft Office suite of productivity software, but can also be purchased as a stand-alone product.
Microsoft Word allows users to create, edit, and format text documents. It offers a variety of features such as spell check, grammar check, templates, fonts, icons, and stickers. Users can also collaborate and share documents with others in real-time. Microsoft Word can work on multiple platforms, like Windows, macOS, smartphones, and tablets. It also allows users to open and edit PDF files, insert pictures from their hard drive or from the web, and use add-ons like dictionaries, mail chimp, and Fax.
