The word adobe /əˈdoʊbiː/ has existed for around 4,000 years, with relatively little change in either pronunciation or meaning. The word can be traced from the Middle Egyptian (c. 2000 BC) word dj-b-t “mud [i.e., sun-dried] brick.” As Middle Egyptian evolved into Late Egyptian, Demotic, and finally Coptic (c. 600 BC), dj-b-t became tobe “[mud] brick.” This was borrowed into Arabic as al-tub (الطّوب al “the” + tub “brick”) “[mud] brick,” which was assimilated into Old Spanish as adobe [aˈdobe], still with the meaning “mud brick.” English borrowed the word from Spanish in the early 18th century.
