Yes. Microsoft Word appeared in 1983, two years before Microsoft shipped Windows to retail customers in 1985. Windows was announced in 1983, which is why the dates can look closer than they are. The Unix part needs a distinction: Unix began in 1969, but the available histories do not establish that Word’s first version ran on Unix or Microsoft’s XENIX.
Was Microsoft Word older than Windows?
Yes. Microsoft dates Word’s first release to 1983, while it says the retail version of Windows shipped on November 20, 1985. That means the Word product family predates Windows as a shipped Microsoft product; it does not mean Word for Windows came first.

Microsoft’s Word history gives October 25, 1983 as the first-release date. A separate Microsoft corporate timeline records Word for MS-DOS 1.00 shipping on September 29, 1983. Those pages describe the 1983 milestone differently, so the safest unqualified answer is simply that Word debuted in 1983. Microsoft Word history · Microsoft corporate timeline

Why do some timelines put Word and Windows in the same year?
Microsoft announced Windows in November 1983, but an announcement is not a shipment. Microsoft’s retrospective says Windows would not ship until two years after it was unveiled; its Windows history gives the retail shipment date as November 20, 1985. Comparing Word’s 1983 release with Windows’ 1983 announcement mixes two different events. Microsoft’s Windows announcement history · Microsoft’s Windows shipment history

When did Word for Windows arrive?
Word for Windows was a later edition, not the original 1983 release under a new name. Microsoft says Word became available for Windows in 1989, four years after Windows shipped to retail customers. The distinction is between Word’s beginnings as a product and the later version designed for Windows. Microsoft Word history
What does “Unix got it first” mean?
Unix predates both Word and Windows: development began at Bell Labs in 1969. The Computer History Museum identifies Ken Thompson and Dennis Ritchie among Unix’s developers. On that broad chronology, Unix came first. Computer History Museum: software and languages timeline
Microsoft also had a documented connection to Unix history. In 1980, the company announced XENIX, which Microsoft described as “a portable, UNIX-based operating system for 16-bit microprocessors.” That establishes Microsoft’s involvement with a Unix-based operating system; it does not establish that the first Word version ran on Unix or XENIX. The platform for Word’s initial release should not be inferred from the XENIX announcement alone. Microsoft Learn: Microsoft history, 1980

How quickly did Word for Windows gain ground?
The Computer History Museum’s 2014 account says Word for Windows generated over half of worldwide word-processing market revenue within four years of its 1989 release. The museum does not provide the underlying calculation or dataset on that page, so treat the figure as its attributed retrospective statement rather than a independently verifiable measurement.
