But there are enterprise versions of Word, Excel, and a few others. And it's worth taking a look at what those versions add. By and large, being able to centrally manage and update from the IT department, and even being able to deploy additional content (plug-ins, templates, etc).
So, they're not client-server, but they do add a server into the mix.
The other common set of features is related to distribution and access. Encryption, workflow management, integration into server-hosted software, etc.
At a certain point, I think that enterprise software development starts to look like enterprise IT consulting. The line between then is pretty blurry, and I think that the really successful enterprise software shops are the ones that don't have an allergic reaction to doing consultant-y things as part of the product/services they offer.
Regardless, the purpose and core features of Word and Excel have not changed in 20+ years. MS Word is a Word Processor. Its purpose is to input and format text. Excel is a spreadsheet. It's purpose is to be an interactive way to organize data in tables.
Mentioning them as an example of "Enterprise Software" without specifically clarifying the Enterprise-features you're talking about is a mistake at best and disingenuous at worst.
