“

Latin ērigō joined ē-, “out of,” with regō, “to direct or guide,” to make a verb meaning “raise” or “set upright.” Its family includes direct and correct: both carry the old image of guiding something along a straight course. By the early 15th century, medical writers were already using erection for penile stiffening; by the 1590s, it could also describe putting up a building. So the same word can summon either scaffolding rising over a street or a very different kind of bodily “setting up.”
