Etymology: Ancient Greek had a tidy pair of words here: "adelphós" meant "brother," and its derivative "adelphikós" meant "brotherly." English borrowed the adjective from that Greek form, so "adelphic" carries the Greek idea of brotherly relation rather than a modern invention built from scratch. The Greek root "adelph-" literally points to a shared womb, since "adelphós" was formed from "a-" (together) and "delphús" (womb), so the word for brother once emphasized common birth. The suffix "-ic" is the familiar Greek-derived adjective ending, the same one found in words like "heroic" and "public." Attaching it to the Greek stem produced an adjective meaning "of or relating to brothers," which English writers have used to describe the bonds between male siblings.
