Why is Safari creating links to Wikipedia?

[Blevins]

I think this just started happening when I updated Safari a couple days ago. On certain webpages, random words are… linkified. When I put my cursor over the link it says 'view (that word) definition from Wikipedia'. How can I turn this off? Thank you!

I dont use Safari so I'll try to point you in the right direction

Look at addons/extension - it'll be one of those - if you are not sure search about each addon or disable one at a time and test
