# 寝る vs. 眠る, what's the real difference?

What's the real, definite difference between 寝【ね】る and 眠【ねむ】る?

I know they both mean "sleep", but also that each carries some additional (sometimes, figurative) meanings.

Where do the meanings overlap? In what scenarios are they interchangeable?

this website had a long and detailed explanation it did the trick for me: maggiesensei.com/2011/05/27寝るneru-vs-眠るnemuru-sleep-related-expressi‌​ons/ –  yadokari Oct 4 '11 at 19:36
Why does typing '!!' in the topic title convert it to a '?' ? –  istrasci Oct 4 '11 at 19:37
The link in yadokari’s comment should be maggiesensei.com/2011/05/27/…. –  Tsuyoshi Ito Oct 4 '11 at 19:55
@istrasci: There is some mechanism to remove multiple exclamation marks. See meta.stackexchange.com/questions/99871/…. But I do not know why two exclamation marks are converted to a question mark. –  Tsuyoshi Ito Oct 4 '11 at 20:52
@istrasci I've added it back for you ;) –  Pacerier Oct 5 '11 at 7:36

go to bed, be in bed.
Does not imply you sleep, since you could be listening to the radio, watching TV…

to sleep, not be awake.
Physiological state.
毎日何時に眠っているか当然に分からない！

I think that's supposed to be 眠る. –  jkerian Oct 5 '11 at 15:49
Do you mean "Does not necessarily imply you sleep"? Because it can mean "to sleep, not be awake". –  istrasci Oct 5 '11 at 17:46
@istrasci: "not(imply(A))" is different from "imply(not(A))", so "necessarily" is redundant. –  Axioplase Oct 6 '11 at 3:56
@Axioplase - logically, touche. From a natural language standpoint, I don't think a lot of people would read it that way. –  istrasci Oct 6 '11 at 14:15

What you explained is the difference between 寝ている and 眠い, not between 寝る and 眠る. –  Tsuyoshi Ito Oct 5 '11 at 10:44
you are right. actually. it is quite difficult to explain japanese vocab in overall as each words has so many meanings :) –  kitokid Oct 5 '11 at 12:32
