Etymology

It is borrowed from Late Latin posthumus,[2][3][4][5] with the English suffix -ous.[2][3] The Late Latin word is an alteration of Latin postumus (“last, last-born, born after the father's death”),[2][3][5] the superlative corresponding to posterus (“coming after, later”),[2][3][6] formed from post (“after”).[2][7][8] The h came from a folk-etymological association with humus (“earth, ground”),[2][6][4][8] or, as Servius explained it, with humō (“to bury”),[2][5][3] as if the child were born after the father was put in the ground.[3][8][5] An adjective posthumus (“born after the death of the father”), in the Latin form, is recorded earlier as an epithet,[9][2] and the word is sometimes spelled without the h, after the classical Latin form.[2] Etymonline notes an older word for the same idea, Old English æfterboren (“after-born”).[5]

Earliest recorded meaning

Occurring, arising or continuing after death: 1608, in a sermon by Bishop John King.[2] The Latin-form posthumus, born after the father's death, appears before 1464 as the epithet of a prince in Capgrave's Chronicle,[9][3] and as an English adjective from before 1522, in Gavin Douglas's Æneid.[2] Etymonline dates posthumus to the mid-15th century.[5]

Semantic evolution

In Latin, postumus meant "last of all" and was often used of a child born after the father's death, his last possible offspring; this gave the word its association with the time after death, which in turn suggested the link with humus and humāre.[10] In English the general sense "after death" came first (1608), followed by the child born after the father's death (1640) and the book published after its author's death (1668).[2] Merriam-Webster Unabridged, however, dates the book sense to 1608 and lists the child first.[6] A noun posthumous, a posthumous child, was used from before 1648 to 1718.[2] Johnson (1755) defined it as done, had or published after one's death.[11]
