what is word wrap??

Word wrapping is when a line of text automatically "wraps" to the next line when it gets to the end of a page or text field. This is different than a "word rap," which involves rhyming words to a rhythmic beat, though that may be more fun than typing. Most word processing programs use word wrap to keep the text within the default margins of the page. Without the word wrap feature, text would continue on one line until the user pressed "Enter" or "Return" to insert a line break.
