Is there a compressed directory of naming variables?

Question

There are many different styles of variable names that I have come across over the years.

The current Wikipedia entry in naming conventions is pretty bright ...

I would like to see a short catalog of naming variables, denoting it with a name / description and some examples.

If the agreement is particularly favorable to a particular community of the platform, this is also worth noting.

I turn this into a community wiki, so please create an answer for each agreement and edit if necessary.

Einar Hoest " Java-" .

He analyzed the grammatical structure of the method names along with the structure of the method bodies and collected information such as:

add- [noun] - * These methods often have parameters and create objects. They very rarely return field values. The phrase appears in almost all applications.

etc., compiled from hundreds of open source projects.
