Standalone copies of MS Word are pretty difficult to find and even if you locate them, they end up costing as much as MS Office. Therefore, one has to purchase the entire Office package to get access to word. However, the processor does not come for cheap and more often than not, it is generally bundled into the Microsoft Office package.
And, if we are to rank a word processor solely on popularity and versatility, Microsoft Word definitely takes the cake.
In the world we live in, it is almost impossible to get work done without a fantastic word processor.
