What does dulled mean?
Dulled is the past tense and past participle of the verb "to dull," meaning to make or become less sharp, bright, intense, or lively. Its most concrete use applies to blades and tools that have lost their cutting edge through wear. More broadly, and more frequently in modern usage, it appears figuratively: emotions can be dulled by grief or medication, senses dulled by fatigue, and mental acuity dulled by repetitive routine. It also describes colors, sounds, or surfaces that have lost their brightness or clarity, as when sunlight dulls paint over time. The word carries a connotation of gradual loss or erosion rather than complete absence — something dulled still exists but has diminished in force. Derived from Middle English "dul," meaning slow-witted or blunt, "dulled" remains a versatile and evocative choice for describing anything that has lost its former keenness, whether physical or metaphorical.

Etymology of dulled
Dulled derives from the Middle English adjective "dul" (meaning slow-witted, blunt, or insensitive), which came from Old English "dol," meaning foolish or dull-headed.
