Okay so talking about
LinkText: You need to mention the complete Link Text to access the element.
PartialLinkText: You just have to type the part of the text you know and the rest is taken care by Selenium.
The format for both are same
The complete link text was Wikipedia Foundation so I just metioned Foundation and it works. This way you can use PartialLinkText in selenium.
Hey @Jino hope this helps.
