Posthumous meaning

1. born after the father's death
2. published after the author's death
3. arising or continuing after one's death

The word posthumous is associated with death, both in meaning and in form. Our word goes back to the Latin word postumus, meaning “last born, born after the death of one's father, born after the making of a will,” and “last, final.” Postumus was largely used with respect to events occurring after death but not exclusively so, since the word was simply one of the superlative forms of the adverb post,“subsequently, afterward.” 


Because of its use in connection with death, however, later Latin writers decided that the last part of the word must have to do with humus, “earth,” orhumāre, “to bury,” and began spelling the word posthumus.This form of the Latin word was borrowed into English, being first recorded in a work composed before 1464.


 Perhaps the most telling use of the word appears in the poet Robert Southey's comment on the rewards of an author: “It was well we should be contented with posthumous fame, but impossible to be so with posthumous bread and cheese.”
