Technical editing is when someone reads through a piece of writing, like a science report or a manual for a toy, and makes sure it all makes sense and is easy to understand. Just like when you draw a picture and your mom or dad helps you fix any mistakes, technical editors help adults fix their writing mistakes, like spelling errors or confusing sentences. They also make sure that the writing follows the rules of grammar and punctuation. This helps people who read the writing later to understand what the writer meant to say. It's like having a superhero who makes sure that everything looks good and is easy to use.
