dullness (noun), dully (adverb)
Dull, meaning ‘stupid or slow in understanding’ (when referring to people) or ‘blunt‘ when referring to edges or points, dates back to around the year 1200, in the form of the Middle English adjective dul or dulle (dil, dill and even dwal were also dialectal variations at the time). Its origin is uncertain. Some linguists trace it back to the Old English adjective dol (foolish or dull-witted), or a siilar, unrecorded adjective, while others think it came into English from the Middle Low German dul, because there is a gap between when the Old English term disappeared and the Middle English dull appeared. Either way, it can be traced back to the Proto-Germanic dulaz, and possibly the Proto-Indo-European root dhul-, from dheu– (dust, vapor or smoke). Dull is related to the Old Frisian dol (reckless), the Middle Dutch dol or dul (stupid, foolish or crazy), the Old Saxon dol and Old High German tol (foolish or dull), the German toll (‘mad or wild,’ also used colloquially now as ‘great’ or ‘cool’), and the Gothic dwals (foolish), as well as the Greek tholos (mud or dirt), the Old Irish dall (blind), and English words such as fume, funk, perfume, typhoon and typhus. The meaning ‘not pleasing, tedious or uninteresting’ appeared in the late 14th century, and the adjective’s sense expanded to describe colors that are not bright or clear in the mid-15th century, and (originally figuratively) to a sensation or pain that is not sharp or intense in the early 18th century. The verb, meaning ‘to lessen the vigor, activity or sensitiveness’ of something, also dates back to around the year 1200, and comes from the adjective. The meanings ‘to make blunt or less sharp’ (about edges or points) and ‘to make less bright or clear’ (of colors) both appeared in the late 14th century. The intransitive sense, ‘to lose vigor or intensity,’ is also from the late 14th century.
