Did you ever struggle with more than one language on a WordPress blog? 
In a world of globalization those struggles reach me very often.
This plugin has the ability to store language codes the in post meta data to have articles with different languages on the same page. This might be interesting for blogs who only need sometimes a different language.
One of those is the following case: 
The boss is writing articles in english but its a german company and needs some articles in german too. 
But the second language articles are unique and not only translations.
You maybe think that would be quite simple using WPML. But what are you doing if you need both languages on the start page? 
For this special case, we wrote a plugin, which is able to show all languages on the home page and manipulates the query if some language is chosen. 
It also makes a difference in terms of SEO as it changes the line
<html xmlns=”http://www.w3.org/1999/xhtml” dir=”ltr” lang=”en-EN”>
according to your language.
For a real working experience you can use it in combination with the <a href="https://wordpress.org/extend/plugins/no-function-language-widget/" title="no function language widget" rel="ugc">no function language widget</a>.

If you don't need a full multilingual plugin, but have single articles in a different language.

Allows you to set the language of individual posts and pages and to summarize 
them in other languages.
The excerpts are automatically inserted right before the post content, with the 
correct language attribute. The correct language attribute is also set on the 
post titles and original content.
If you were using this plugin prior to version 1.0 you will have to migrate 
your posts and pages.
<ol>
<li>Make sure your back-up your database</li>
<li>Select the same 2 languages you were previously using in the “Site languages” 
option</li>
<li>Press the “Migrate” button on the settings page</li>
</ol>
