What does dulling mean?
Dulling is the present participle and gerund of the verb 'dull', describing the process by which something loses sharpness, brightness, intensity, or liveliness. It applies literally to physical objects — a blade being dulled by use, or sunlight dulling a fabric's color — and figuratively to sensations and faculties, as in pain being dulled by medication or grief dulling someone's appetite. It can also describe the wearing-down of interest or enthusiasm, when repetition or tedium makes an experience feel flat. The word carries a quietly negative connotation: whatever is being dulled is understood to be diminishing, eroding, or fading, usually gradually and often imperceptibly. Derived from Old English 'dol', meaning foolish or slow-witted, the root also gave English the words 'dolt' and 'dullard'. Dulling remains common in everyday writing about wear, anesthesia, and emotional flattening, making it a precise and evocative choice whenever gradual loss needs naming.
Present participle of 'dull': to make or become less sharp, bright, intense, or lively.

Transitive when something acts on an object ('the drug dulled the pain'), intransitive when the subject itself loses quality ('her senses were dulling').
The act or process of making something less sharp, bright, or intense.
"The dulling of his hearing came on gradually over several years."
The same Old English root that gave us 'dulling' also gave us 'dolt' — to be dull was originally to be slow-witted, before the word spread to blades, colors, and pain.

Etymology of dulling
Dulling derives from the adjective 'dull', which comes from Old English 'dol', meaning foolish, silly, or slow-witted. The same root produced Middle English 'dullen', meaning to make or become dull, and is related to the German 'toll' (wild, mad) and to the English word 'dolt'. Over time the sense broadened from mental slowness to physical bluntness, dimness, and monotony, so that by the modern period 'dull' and its participial form 'dulling' could apply equally to edged tools, colors, sounds, emotions, and company.
