Etymology
The word 'declining' originates from the Latin verb declinare, which is a compound of the prefix de- (meaning "down from") and the verb clinare (meaning "to bend" or "to lean"). The literal sense was "to bend down" or "to turn aside." This concrete image evolved in Medieval Latin to signify a metaphorical "turning away" from a course, leading to meanings of polite refusal. The core notion of a downward trajectory was retained and extended to abstract concepts like decreasing numbers or deteriorating health. The present participle suffix -ing was added from Old English, grammaticalizing the state or action into its current adjectival and verbal forms.
