Note: The nominative was held to be the primary and original form,
and was likened to a perpendicular line; the variations, or oblique
cases, were regarded as fallings (hence called casus, cases, or
fallings) from the nominative or perpendicular; and an enumerating of
the various forms, being a sort of progressive descent from the
noun's upright form, was called a declension. Harris. Declension of
the needle, declination of the needle.
