About This Root

From Latin fīlius (son) and fīlum (thread) — two distinct Latin words that converge in English. The "son" branch gives filial (of a son/daughter) and affiliate (to adopt as a son). The "thread" branch gives filament (a thin thread), file (documents threaded together), filigree (thread-work), and profile (drawn in outline, like a thread). Context determines which meaning applies.
