Sorry, but this sentence doesn't make sense. :( I asked my father, as well, and we're pretty sure it's not an English expression. I also couldn't find a definition for 覆い尽くす in the wwwjdic, so I don't know what to suggest instead of "hiding off"...

Welcome to the Tatoeba Project!

This sentence and its Japanese version originate from Tanaka Corpus, as far as I can judge, and, thus, there's no guarantee that both sentences are natural and error-free.
I'm not sure, but 覆い尽くす seems to be a compound verb made of 覆う and 尽くす. As far as I know, in such constructions 尽くす (尽す) means the full completeness of the action (just like "verb + off" in English). That is, if 覆う means "to cover/to hide" then 覆う尽す "to cover/to hide completely".
Unfortunately, English and Japanese are not my native languages so I maybe mistaken. It would be nice if some native speaker has taken a look at these sentences.

The Japanese sentence isn't grammatically wrong, but I'm not sure what it means. It seems to be using "覆い尽くす" metaphorically. It doesn't seem to me a good example sentence for the learners, anyway.

I added a sentence using "覆い尽くす".

I hope it will make clear what this verb means.


If you are studying Japanese and make use of sentences in Tatoeba, I strongly recommend you to ignore all the sentences not owned by a native Japanese. Otherwise you should ask someone whether it's all right.
