### 9.6 `\fussy` & `\sloppy`

Declarations to make TeX more picky or less picky about line breaking. Declaring `\fussy` usually avoids too much space between words, at the cost of an occasional overfull box. Conversely, `\sloppy` avoids overfull boxes while suffering loose interword spacing.

The default is `\fussy`. Line breaking in a paragraph is controlled by whichever declaration is current at the end of the paragraph, i.e., at the blank line or `\par` or displayed equation ending that paragraph. So to affect the line breaks, include that paragraph-ending material in the scope of the command.
