Overly Broad or Narrow Definitions
A definition is no good if it defines its subject with overly wide or narrow parameters. For example, "a shape with four sides of equal length" is not a good definition for 'square'. Why? Not only squares have four sides of equal length; rhombi do as well. This is proven by identifying not only the term being defined, but also the conditions in the definition. Likewise, defining a 'rectangle' as "a shape with four perpendicular sides of equal length" is not valid because it is too narrow.

“Somewhere between the overly intrusive parent and the parent who forgets about us after we’re out of the house is the ideally empathetic parent who recognizes the relativity of choice, the errors of his or her own way, and our need to find our own way and who can stay with us at a respectful distance while we do it.”
—Roger Gould (20th century)
“Where the broad ocean leans against the land.”
—Oliver Goldsmith (1728–1774)
“Less than five hundred souls inhabit the three quaint streets and the few narrow by-lanes and scattered farmsteads that constitute this small, decaying watering-place which may, indeed, be called a “backwater of life” without disrespect to its natives who possess, to this day, a salty individuality of their own.”
—Dylan Thomas (1914–1953)
“The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babies—if they take the time and make the effort to learn how. It’s that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.”
—Pamela Patrick Novotny (20th century)
