一睡もできなかったって英語でなんて言うの？

まず、本来は、このように一回きり（一回ごと）の「～出来る」は canではなく、 be able to　を使うのが正式ですが、 be able to は、ややフォーマルになりますので、 会話では、can (この場合、過去ですのでcould)で、代用することがよく行われています。 一番簡単な例文が２つめので、 「まったく眠れなかった」が直訳です。 at all 「まったく」 最初と最後の例文ですが、 not get a wink of sleep　 あるいは　 not sleep a wink　で 「まったく眠れない」という意味になります。 「一睡も」の「も」のニュアンスを出すのは、この場合、even ですので、 どちらにもevenがついています。 なお、~be able to の否定には、be unable to～もありますが、 be unable to～を使うと、かなりフォーマル（堅い表現）になりますので、 例文は　not be able to~としてあります。（２つめの例文） ご参考になりましたら幸いです。

If you would like to explain to someone that you could not sleep at all last night, you can say something like "I did not even get a wink of sleep in last night". A "wink of sleep" basically means the smallest/shortest amount of sleep, so saying that you did not even get A WINK OF SLEEP would mean that you did not get any sleep the night before.

In the first two example sentences, we actually have the same sentence structure but either use the auxiliary, "to do," or we use the past tense, "couldn't," to describe that we didn't have the capability to sleep.

Saying that "I didn't get any sleep last night" means that you couldn't fall asleep at all last night. If you didn't get any sleep last night, there is a high probability that you will be feeling tired today. Insomnia is a medical term that is used to refer to people who suffer with the inability to fall asleep.

I couldn't sleep last night. I got no sleep last night at all. I didn't sleep a wink last night. When you want to tell others that you were unable to sleep the night before, you can use one of these three sentences. The first sentence is a very straight forward one, but the second two using, 'at all,' and, 'a wink,' a little but more native. I hope that helps. Have a great day. Will

Some people when they cant sleep will call it insomnia. Acute insomnia is when it happens for a short period of time, but normal insomnia can last longer and can cause a strain on daily life it is keeps happening. Being restless can mean you was distressed whilst trying to get to sleep and could have been tossing and turning all night until a person is comfortable enough to sleep.

It happens to many of us that sometimes we cannot sleep. We may be stressed out about something or we may have slept really late the day before and for this reason, we cannot sleep. "I had a hard time sleeping last night". A hard time means that it was very difficult for you to sleep. Maybe you slept in the end, but it was many hours after you went to bed "I didn't sleep very well last night" is a very simple explanation that you can use in any situation. It confirms that you did fall asleep but that maybe you woke up a lot or went to bed late and got up early.

I had trouble sleeping last night. This expression is very simple and to the point. You are telling the person you are talking to that you had trouble falling asleep or you did not have a good night's sleep. Last night I couldn't fall asleep for the life of me! In this expression, you are emphasizing to the person you are talking to how frustrated you are due to not being able to sleep the night before. This phrase "for the life of me" can be used for different things, it basically means you are emphasizing that you cannot do something, in this case, fall asleep but can be used in other situations for example "This exam is going to be hard, I cannot understand the information for the life of me!"

shut-eye: idiom word that means sleep. If you are just making a statement You can say "I had a hard time sleeping last night." or "I did not get any sleep last night." When making a casual conversation you can say all three statements but you can use idiom vocabulary or idiom phrases like "I didn't get any shut-eye." You wouldn't really want to use idiom phrases in a business or professional setting. It is more for casual conversation.
