[jprete]

One way to see wordiness:

When you’re speaking, whatever your thoughts are have to come in the order that you think them, because people are used to being interrupted and therefore don’t want to stop talking to pick the right wording. So they say things in a very long way, just as they thought of them, in a disorganized jumble not dissimilar to this paragraph.

Writing, however, can be edited to make points clearly, without irrelevant detail, and logically ordered.
