Editing

Editing:

A stage of the writing process in which a writer strives to improve a draft by correcting errors in grammar, spelling, formatting, and other mechanics (1) 

Examples

Before editing
I think that the the olympics are about trying your best and make history. Its not about the platform. or the medals it’s about racing yourself and constantly improving to beat yourself.

After editing
The Olympics are about trying your best and making history. “Winning” is not about the platform or the medals. It’s about racing against yourself and constantly improving to be the best you can be.

Additional Discussion:

Many people make a distinction between editing and revising. Common understanding in the upper grades here at Brookwood is that editing deals more with the nuts and bolts of writing: spelling, word placement, grammar conventions, formatting, and other mechanical aspects of writing. Editing involves (but is not limited to) proofreading. Revision literally means to see again, to look at something from a fresh, critical perspective. “It is an ongoing process of rethinking the paper: reconsidering your arguments, reviewing your evidence, refining your purpose, reorganizing your presentation, reviving stale prose” (The Writing Center, UNC College of Arts and Sciences).

One way to look at it is to imagine that a writer revises with an eye to her or his message—what, exactly, am I trying to say? That same writer edits with an eye to the reader—how can I get my audience to understand exactly what it is I am trying to say?
