"Language most shows a man; speak so that I may see thee."
Ben Johnson (Poet b. 1572)
The phrase first and foremost must fade away. Now. Writing both is a redundancy. If something is first - as in the first reason you do something, or the first of anything, you don't need foremost. Foremost means: leading, principal, FIRST, premier, top, best, and more. First means: FOREMOST, principal, top, and more. These words mean the same thing. That means that to always be using them together is redundant. Who started this? Someone has to stop it first. Let it be me and you; should you choose to take the challenge. I challenge you to scour this phrase from your writing. Firstly, your writing will be more concise, but the foremost reason for cutting this phrase from your writing is that it is redundant. Lose redundancy in your writing, and your writing will be more enjoyable to read, and more understandable.
