Frequently Asked Questions

What is the difference between function and functionality?

A function is one specific thing something does, such as a calculator's square-root function. Functionality is the whole range of things it can do, so a calculator's functionality includes all of its functions together. Function counts individually; functionality is normally treated as a mass noun.

What is the difference between functionality and usability?

Functionality is about what a product can do; usability is about how easily a person can do it. A tool can have enormous functionality and still be almost unusable if the controls are confusing.

Is 'functionalities' correct?

It is acceptable but rare, and it sounds bureaucratic. Use it only when you mean several separate feature sets, such as 'the reporting and billing functionalities'; otherwise keep functionality singular.
