What names do you find yourself prepending/appendi

Question

Which nouns do you find yourself putting regularly at the end of your classes?

For example, I have a habit of sticking Info onto classes that pass information around but don't do a great deal:

• ImportInfo
• SiteInfo

Or for Coordinating classes:

• UserManager
• SecurityManager

I end up using Builder quite often for string related classes, even if it barely does any building:

• TemplateBuilder
• HtmlBuilder

And of course the timeless Helper/Utility class:

• PhraseHelper
• NumberUtility
• FileHelper

Have you got any good, by which I mean concise and descriptive, nouns or words you regularly use to denote the class' main role?

This question is aimed at the .NET world, but can extend to Java, C++, Python and so on.

Answer 1

why of course...

Base

works both sides.

Answer 2

If my class is specifically doing calculations, I will prepend Calc

Examples:

• TaxCalc
• TipCalc
• DateCalc
