联想 dull（钝的/乏味的）：一把钝刀切不动东西，让人提不起兴趣，加上 -ness 变名词，就是 dullness。
语域：neutral 常见场景：academic or literary writing、everyday descriptions of objects or experiences dullness 是 dull 的名词形式，通常用于书面或较正式的表达，在口语中也能出现。具体含义要看搭配：形容事物时多指“乏味”，形容头脑或感知时多指“迟钝”，形容表面或刀刃时多指“暗淡/钝”。日常口语若觉得太正式，可换用 boredom、slowness、bluntness 等更具体的词。
没有常见单词与 dullness /ˈdʌlnɪs/ 完全押韵。下面这些 -ness 结尾的词只是拼写相似，重读元音不同（例如 happiness 为 /hæ/，business 为 /bɪ/），不是真正的押韵。注意 business 看似押韵，但元音是 /ɪ/ 且后缀弱读，所以与 dullness 读音不同。
