Widows and Orphans (newspaper terminology)

“Widows” and “orphans” are words (or short lines) at the beginning or end of a paragraph that appear at the top or the bottom of a column or page. The term “widow” originally applied to both and has been cited in print since at least the early 1900s. “Orphan” (at the bottom of a column or page) has been cited in print since at least 1979, when computer word processing programs began offering “widow and orphan control.”
 
There are several colorful “widow” and “orphan” sayings that have developed. “Kill the widows” has been used in newspaper editing since at least the 1920s and “kill widows and orphans” since at least 1986. “A widow has a past, but no future” and “An orphan has no past, but it has a future” have been used since at least the early 1990s. Another saying is that one should look up to a widow and look down to an orphan.
 
   
Wikipedia: Widows and orphans
In typesetting, widows and orphans are words or short lines at the beginning or end of a paragraph, which are left dangling at the top or bottom of a column, separated from the rest of the paragraph. There is some disagreement about the definitions of widow and orphan; what one source calls a widow the other calls an orphan. The Chicago Manual of Style uses these definitions:

Widow
. A paragraph-ending line that falls at the beginning of the following page/column, thus separated from the rest of the text.
 
Orphan
. A paragraph-opening line that appears by itself at the bottom of a page/column.
. A word, part of a word, or very short line that appears by itself at the end of a paragraph. Orphans result in too much white space between paragraphs or at the bottom of a page.

Remembering the terms
A common mnemonic is “An orphan has no past; a widow has no future” or “An orphan is left behind, whereas a widow must go on alone”.
 
Another way is to think of orphans as generally being younger than widows; thus, orphaned lines happen first, at the start of paragraphs (affecting and stranding the first line), and widowed lines happen last, at the end of paragraphs (affecting and stranding the last line). Orphaned lines appear at the “birth” (start) of paragraphs; widowed lines appear at the “death” (end) of paragraphs.

(Oxford English Dictionary)
widow, n.
Typogr. A short line at the end of a paragraph, esp. one which is set at the top of a page or column, or which contains only (part of) one word, and is therefore considered unsightly.
[1904 Man. Rules Compositors S.S. McClure Co. 25   All running heads are to be set one nonpareil from the body, unless otherwise instructed.

A Widow has a past but no future.  It is the last line of a paragraph set at the top of a page, especially the left-hand page of a multi-column layout.  Widow lines are generally avoided.
 
An Orphan has no past, but it has a future.  It is the first line of a
paragraph, set alone at the bottom of a page, especially the right-hand page in a multi-column layout.  You can read column for page here, incidentally.

I always like the term “widow” as in, a very short line of type, and the expression “Kill the widows” (eliminate the widows in a paragraph) makes me smile.

In printing generally, a widow is the last line of a paragraph that appears at the very top of a page, and an orphan is the first line of a paragraph that appears at the very bottom of a page. Both are considered faults in typography, and automated layout systems have “widow and orphan control” to prevent them by inserting judicious amounts of extra leading between the lines.

A mnemonic device to remember the difference between widows and orphans: You look UP to look out the WINDOW at widow. You look DOWN at the little orphan child. Widows = UP. Orphans = DOWN.
Yeah, I know: Charles Dickens.

Because there are so many paragraphs, there’s a kind of random distribution that happens in books. If you get to the bottom of a page and there’s only room for one more line, and that line is the first line of a paragraph, you will have an odd look at the bottom of that page. This is a widow:

On other pages, just the last line of a paragraph may bump to a new page, leaving a stub of a line at the top. That’s an orphan: ...
