In the craft of writing, there's lots of potholes to avoid. Many of them have to do with distracting the reader. One of the things I have to watch out for in my writing is the echo.
Ever heard of that? I hadn't, until a writer friend started pointing them out.
Echoes are when you use a word repetitively in a short block of text, or even words that sound similar. While an echo can be used to make our work stronger (as in repetition for effect or emphasis), it can also weaken the work when used without thought.
So check your writing! Look for common sounds in a paragraph, or the same word used a few times. Then break out the thesaurus and find a new word! :-)
