Forgive me if my English is wrong, but is
Mice eat all. wrong? I'm sure
Mice eat everything. is more natural, though.
All can't really be used in that sentence as the "all" would be an adjective. Not a noun that can be the target of a verb.
When all is used as a noun it means "Everything possible" or All of someone's possessions. Even so these are mostly used in set expressions
Hence: The mouse gives his all [does everything possible] to eat everything, but lost is all [everything that he owned, perhaps even his life] trying."
Everything significa comer TODO de algo ,por ejemplo un ratón entra en la tienda y al otro día encuentras que le hechó diente a las galletas a la harina ,a la bebida de pepino de tu hermana ( lo dudo) . Pero " all" quiere decir absolutamente todo: los estantes, las sillas ,las botellas ,el detergente ...
So wait, if the mice are eating everything, and the bears are eating everything, and the wolves are eating everything, who's flying the plane?
Apparently in Russia, Bears, Dogs, and Mice are all consuming plagues. Your only hope is to exterminate everything before they reach your house and consume you.
Without context, the Russian sentence says that mice are omnivorous in general, not that they are eating everything right now. I'd translate your sentence as "Мыши поедают всё".
Thank you for being really simple in your explanation. English is my native language but some of the explanations in the comments use lots of grammatical terms which I never understand!
Go to this site
then search for едят, and it will show you the root word and all possible conjugatiшщты
Note: don't use ё, instead use е
все = everybody: Все едят борщ = Everybody eats borsch
все <noun> = all <noun>: Все мыши едят сыр = All the mice eat cheese
всё (with dots) = everything: Мыши едят всё = Mice eat everything
To me it sounds more like "moo-she". But I think, based on the syllable, it should sound like "mi-shi". Could any Russian expert help clarify this ?
Can't claim expertise, but the ы sound is one we don't have in English, nor anything really very close to it, so approximating it in the Latin alphabet is always going to be difficult. Neither oo or i is a great way of representing it.
The TTS isn't bad, IMO, but I think it would also be really worth your looking up YouTube videos for the Cyrillic alphabet in general, and for this letter in particular (there are entire videos dedicated to trying to explain how to produce this letter properly, it's one that many, many learners have issues with), so you can hear it being used by real people in the wild, not just by a creepy computer voice :)
