What the heck is a "basis" anyway?

This is gonna be a rant.

Sorry.

I haven't done a rhetoric rant in a long time, but today, I simply can't avoid it.

It will be short. I promise.

Everywhere I go, I hear this word: basis. And I hate it. Why? Because it's wordy. And I'm not even sure what it means exactly. What the heck is a "basis" anyway? I assume it's related to the word "base," meaning the groundwork of something or the thing on which something is based? But I'm not really sure. All I know is people use the word all the time, resulting in wordy, cluttered sentence constructions. 

 Here are some examples:

I shower on a daily basis.

In the summer months, I mow my lawn on a weekly basis.

I exercise on a regular basis.

I see and hear these phrases everywhere: on T.V., on social media, in church talks, in political speeches, in magazine articles, in celebrity interviews, and more.

Please, everyone, let's put these verbose sentences on a diet, by eliminating the word "basis" whenever possible. The use of a simple adverb will suffice:

I shower daily.

In the summer months, I mow my lawn weekly.

I exercise regularly.


Together, we can change the world.
