Reconstruction

The noun is *saipǭ in Wiktionary,[1] *saip(j)ō(n) in Orel,[2] and *saipjōn or *saipōn in Köbler.[3] Kroonen reconstructs *saipwōn-, and so does EWA.[4][5] LÄGLOS gives the Germanic sources of the Finnish word as *saipōn- and *saipijōn-.[6]

Morphology

A feminine n-stem.[4][2] Two forms have been reconstructed: *saipjōn- with a j-suffix, for the geminate of Old High German seipfa,[4] and *saipōn-, for the lack of umlaut in Old English sāpe;[4] Kroonen unites them in *saipwōn-, which explains both and is echoed in Finnish saippua.[4]

Evidence

The word is attested only in West Germanic: sāpe, Old Frisian sēpe and Old High German seiffa, seipfa.[4] The Old High German noun is found from the 11th century.[5] Finnish saippua, beside saippio and other forms, is a Germanic loan;[6][5] LÄGLOS calls the etymology unproblematic in sound, meaning and cultural history.[6] Latin sāpō (“soap”) was borrowed from Germanic.[4]

Competing analyses

For Kroonen and EWA, Old Norse sápa is a loan from Old English, since it has ā and not the diphthong expected beside the West Germanic forms.[4][5] De Vries rejected that view: he took the Norse word from a Proto-Norse form with -j-, like Old High German seipfa, which Finnish saippio continues, and thought that Norse had both forms.[7] Kroonen notes that the io-suffix of the Finnish word may be Finnish.[4]

Kroonen calls the derivation unknown, but takes the Old English word for "amber, resin" as a sign of a Germanic origin, and calls the link with the Swedish dialect verb sipa (“to flow slowly”) uncertain.[4] Orel derives the noun from *sīpaną "to drip";[2][1] Köbler compares Proto-Indo-European *seip- (“to pour, to trickle”).[3] De Vries thought that soap was first a means of dyeing the hair red, as Pliny reports of the Gauls.[7]

Meanings

  1. soap[4][2][3][1]

Wiktionary suggests that the original sense may have been "amber, resin",[1] and Old English and Old High German also used the word for "resin".[8][5]

Derivatives

  • *saipja- "resin", in the Old English compound stōrsǣp.[4]

Reflexes

  • Old English: sāpe (“soap, resin”)[8]
  • Old Frisian: sēpe (“soap”)[9]
  • Old Saxon: sēpa (“soap”)[10]
  • Old High German: seifa (“soap, resin”)[5]
