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
driver.get("https://www.wikipedia.org/");
driver.findElement(By.partialLinkText("Foundation")).click();
The complete link text was Wikipedia Foundation so I just metioned Foundation and it works. This way, you can use Partial LinkText in Selenium.
Hey @Jino hope this helps.
