The question "Home page" or "homepage"? was closed seven years ago on the following grounds:
This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.
However, a perusal of Hugo's carefully researched answer to the question indicates that the answer is by no means "definitively and permanently answered by a single link to a standard internet reference source." To the contrary, readers who go to merriam-webster.com or to the link provided beneath the posted question by one of the close voters for a definitive and permanent answer will encounter a fundamentally misleading answer to the question—an answer that treats "home page" as the only legitimate spelling.
A tangential issue here is whether the question is of enduring interest to site visitors. In that regard I note that, despite its having been closed for the past seven years, the question has been viewed more than 51,000 times by visitors to EL&U. Clearly, a lot of people are interested in an informed answer to this question.
In my view, Hugo's answer is extremely useful and is a model of the kind of effort that makes English Language & Usage a valuable online resource. It is certainly more useful and valuable than any fifty open single-word request questions and answers selected at random from the pages of EL&U. Please consider voting to reopen this question.
