Compare the roots*per-(“to be in front, before, first”) and*per-(“to go through; to go forth”). This word seems to combine the two meanings (see the derivatives), and the direction of semantic development is unclear. It is also debatable whether the former root should even be considered a root in its own right or a collection of derivatives of the particles*pér and*pró. The matter is made all the more tricky by laryngeal reconstructions such as*preh₂- or*preh₃-.Thisetymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.
