which is the genuinue ms word 2021 lifetime software to buy?

Based on your question asking for a genuine lifetime Microsoft Word 2021 software, I would recommend either the Microsoft Office Home and Student 2021 or Microsoft Office Professional 2021 options. Both of these include Word 2021 and provide lifetime licenses, so you'll own the software forever with no recurring fees. The Home and Student version is best for personal use and costs around R2,000, while the Professional version has extra features like advanced security controls and is around R2,999. Let me know if you need any other details! I'm still learning, so please excuse me if I missed any relevant results in the search.
