Why “filiation” is a great word
FILIATION — [Noun] The condition or fact of being the child of a particular parent or parents, or the line of descent from an ancestor. First attested circa 1520, from French filiation, from Medieval Latin fīliātiōnem (stem fīliātiōn-), from Latin fīlius ("son") and fīlia ("daughter"). Unlike "affiliation" (which implies a chosen, formal alliance) or "lineage" (which suggests a noble, extended pedigree), filiation is the singular, primal tether. It is the cold type on a birth certificate, the shape of a nose repeated in a photograph across three generations, and the silent shock of discovering your father's handwriting in your own—the unasked-for inheritance that is the first and final proof of where we come from.
