Literary notes about Declension (AI summary)
The term "declension" has been used in literature with a rich diversity of meanings and contexts. Classical grammar texts, such as those by Farley and Kittredge, define declension in a precise, technical way—as the inflection of a substantive or noun ([1], [2], [3])—and even extend the discussion to related processes like the evolution of verbal forms ([4]) and changes in Sanskrit by-forms ([5]). At the same time, authors venture beyond mere grammatical description. For example, Santayana employs “declension” metaphorically to illustrate the dilution of pure vitality by nothingness ([6]), while Thomas Jefferson references the term in debates over historical dating ([7]). In a more humorous vein, Rabelais uses it in a proverb about the fortunes of physicians at the decline of diseases ([8]), and Frazer applies it cosmologically to describe the sun’s annual reduction on Midsummer Day ([9]).
