When is "na" used at the end of a sentence?


When is "na" used at the end of a sentence, is it like "ne" or "yo" and has no
meaning really? For example:

> Mata Nihon ni ikitai na.  
>  また、日本に行きたいな。




な at the end of a sentence usually gives the sentence one of the following
five meanings.

> **1. Seeking confirmation**

This usage is probably the most common. The addition of な to the end of a
sentence gives the sentence the tone that the speaker is seeking confirmation.
The speaker does not wish to assert that he is 100% confident about what he is
saying. It does not necessarily mean that he isn't confident, he just doesn't
wish to convey that he is. He wants to give his audience room to disagree if
they want.

An simple example to illustrate some possible translations:

この本｛ほん｝はとても面白い｛おもしろい｝、な？  
This book is really interesting don't you think?  
This book is really interesting, right?  
This book is really interesting, isn't it?

な as used this way is essentially equivalent to the sentence final particle ね
except it is harsher and more masculine sounding.

> **2. Rhetorical**

This usage is related to the first usage (actual Japanese speakers might not
consider them different) except it doesn't translate well into English. This
usage essentially serves as a way for the speaker to reduce the assertiveness
of a statement without actively seeking confirmation. In usage 1, the speaker
is expecting the listener to say something and agree with him. In this usage,
the speaker isn't necessarily expecting anything, he just wishes to introduce
a topic without making an abrupt statement.

Consider the difference in tone between the following:

  * I would like to go to Japan again. (picture a person stating that as a fact with a completely expressionless face).

  * I'd reaaaaallllyyyy like to go to Japan again. (said with "really" drawn out and with changing pitch).

They essentially mean the same thing but the first is merely a statement of
fact while the second is almost about introducing a topic.

This is the use in your question and the second example above is a reasonable
translation (the "reaaaaalllyyy" should not be in the translation and was only
included to illustrate the tone).

> **3. Negative imperative (Rough)**

The **addition of な to the dictionary form of a verb** produces the negative
imperative (command). This is very harsh and not used often in actual
conversation I think.

食べる｛たべる｝な! - Don't eat it!  
行く｛いく｝な! - Don't go!

A more acceptable negative imperative would be:

食べないでください。 - Please don't eat it.  
行かないでください。 - Please don't go.

> **4. Positive imperative (informal and abbreviated)**

The **addition of な to the masu-stem (i-stem, ます形) of a verb** produces the
positive imperative (command). This is quite easy to mix up with usage 3. It
may help to understand that the な in this case is actually an abbreviation of
なさい. I'm not certain how formal this sounds to a native.

食べ｛たべ｝な! - Eat it!  
行き｛いき｝な! - Go! (Get out!)

The unabbreviated versions are:

食べなさい。 - Please eat it.  
行きなさい。 - Please go.

> **5. Expressing the concept of wonder (～かな)**

Lastly, when a **sentence is followed by かな** it expresses the speakers sense
of uncertainty about how something became the way it is. This is usually
translated as "I wonder how..." or "I wonder if..." in English.

おいしいかな。 - I wonder if it's tasty. (I wonder if it's any good.)

Hope this helps. If I missed anything or am incorrect, please point it out in
