Reconstruction

Wiktionary reconstructs *opan for Proto-West Germanic.[1]

Etymology

It is inherited from Proto-Germanic *upanaz (“open”),[2][3] which Orel writes *upanaz, Köbler *upena-, *upana-, and EWA *upana-.[2][4][3]

Morphology

An adjective.[5][3] EWA finds that it looks like a verbal adjective, with the suffix *-ana- or *-ena-, a passive sense and predicative use, but that no strong verb belonging to it can be found; it therefore connects it with *uppa or *uppē "up, upwards", the sense passing from "lying on top" to "open".[3] Orel likewise derives it from *uppa with the suffix of the strong past participle,[2] and Berr calls it a past participle "opened".[6]

Evidence

The adjective is attested in Old English open,[7] Old Frisian epen, also open,[8] Old Saxon opan[6] and Old High German offan, the last from the Abrogans on.[3] In Old Dutch, ONW records ophan in Williram's commentary on the Song of Songs of 1100,[9] and EWA counts it as a single record of about 1100.[3]

Competing analyses

Boutkan and Siebinga derive open from *upana-, like the other West Germanic words, but epen, like Old Swedish ypin, from *upina-, which agrees with the past participles of these dialects.[10] EWA also takes epen for a different formation, from *upena-, and the Old Frisian forms with o for borrowings from Middle Low German or Middle Dutch; it holds that the form in *-ena- arose only through a secondary link with the verbal adjectives.[3] Szemerényi's derivation from an adverb *upa-nē "from above" is rejected by EWA, because no such adverb is attested,[3] and Boutkan and Siebinga object that it leaves epen and ypin unexplained.[10]

Meanings

  1. open[1]

Old Saxon also used the adjective for "clear" and "sincere",[5] Old High German for "evident", "clear" and "public",[3] and Old Frisian for "not held in common, free", for a lawsuit not yet decided, for "public", and as a noun for an open wound.[8]

Derivatives

  • *opanōn "to open", which Wiktionary reconstructs;[11] Orel derives the Proto-Germanic weak verb *upanōjanan from the adjective, with Old English openian, Old Frisian epenia, Old Saxon opanon and Old High German offanōn.[2]
  • *opanbārī "evident, public", which Wiktionary reconstructs;[12] EWA lists Old High German offanbâri (“evident, public”), from the 10th century, with its Middle Low German, Middle Dutch and Old Frisian counterparts.[3]

Reflexes

  • Old English: open (“open, evident, clear”)[7]
  • Old Frisian: epen (“open, free, public”)[8]
  • Old Saxon: opan (“open, clear, sincere”)[5]
  • Old Dutch: ophan (“open, accessible”)[9][3]
  • Old High German: offan (“open, evident, clear, public”)[3]
