What is the abbreviation of word documents?

There isn't a universally accepted abbreviation for "word documents."

However, depending on the context, you might see these used:

* DOC: This refers specifically to the file extension for Microsoft Word documents.

* WD: This is a common abbreviation used in some contexts, but it can be ambiguous as it could also stand for other things.

* Docs: This is a more informal abbreviation, often used when referring to documents in general, not just Word files.

It's best to be clear and specific in your writing, using the full term "word documents" or specifying the file extension (.doc or .docx) if necessary.
