Synonym discussion
Sense: adjective/1
All four adjectives describe movement toward a lower position or level, but they differ in register, speed, and typical context. 'Downward' is the most neutral and factual; it simply describes direction without implying how fast or why ('a downward slope', 'downward pressure'). 'Descending' is more formal and often suggests a controlled, gradual process ('the descending aircraft', 'descending notes of a scale'). 'Falling' implies faster, uncontrolled, or gravity-driven movement ('falling leaves', 'falling prices') and carries a more dramatic tone. 'Declining' is used almost entirely in metaphorical or statistical contexts ('declining enrollment', 'declining health') and focuses on reduction over time. Compare: 'The plane was in a downward descent' (neutral fact), 'The plane was descending' (controlled action), 'The plane was falling' (emergency).

Etymology
Formed from the adverb 'down' (from Old English 'dūn', meaning 'from a higher to a lower position') plus the suffix '-ward' (from Old English '-weard', meaning 'in the direction of'). The word has been used in English since the Old English period as 'dūnweard', originally as an adverb. The adjective use developed later in Middle English.
