## AI Etymology
Compactness comes from compact + -ness, from Latin compactus, past participle of compingere ('to fasten together'), from com- ('together') + pangere ('to fix, fasten'). The historical trail runs through compingere in Latin and pangere in Latin. Morphologically, compactness is transparent: it draws on compact + -ness, from Latin compactus, past participle of compingere ('to fasten together'), from com- ('together') + pangere ('to fix, fasten'). Used as a noun, compactness now means "the quality of being densely packed or neatly small in size", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in related forms such as compact, compaction, and compactly. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
