permalink
Synonym discussion
Sense: noun/1
For noun sense 1, permalink is used when the important idea is stability over time. A link can be any clickable connection, so it is much broader. URL is the technical term for a web address; it can describe a permalink, but it does not itself suggest that the address will stay fixed. Web address is the everyday general phrase and is also broader than permalink. Short link points to a compressed address made to save space, especially in messages or social media posts; it may redirect and is not the same idea as a permanent address. A blog post may have its own permalink, while a short link is often created just to make sharing easier.

Etymology
Permalink is a modern internet word formed in English from permanent and link. It became common when blogs and websites needed fixed addresses for individual posts, pages, and comments, not only changing front pages.
