Reconstruction

Ringe and Taylor reconstruct *dādi for Proto-West Germanic,[1][2] and Wiktionary has the same form.[3]

Etymology

It is inherited from Proto-Germanic *dēdiz (“deed”),[1][4] which Kroonen cites by its stem *dēdi-, Orel as *đēđiz and Köbler as *dēdi-, *dǣdi-.[4][5][6] The Northwest Germanic change of *ē to *ā made Proto-Germanic *dēdiz into Proto-Northwest Germanic *dādiz, the source of Old Norse dáð and of the West Germanic words.[7] Proto-Northwest Germanic *dādiz then gave Proto-West Germanic *dādi.[1]

Morphology

A feminine i-stem.[8][9] Ringe and Taylor's Proto-West Germanic paradigm has the singular nominative and accusative *dādi, genitive, dative and instrumental *dādī, and the plural nominative *dādī, accusative perhaps *dādį̄, genitive *dādijō and dative-instrumental *dādim.[8] The long *-ī of the dative and instrumental singular would not be expected from Proto-Germanic; they take it to have been adopted from the genitive in Proto-West Germanic, as the Old High German feminine dative and instrumental in -i, not lost after heavy stems, suggests.[8] Kroonen takes the Proto-Germanic noun for a ti-stem from the root of *dōn- "to do".[4]

Evidence

The noun is attested in all the West Germanic languages: Old English dǣd, Old Frisian dēde, Old Saxon dād and Old High German tāt.[2] In Old English the vowel became West Saxon ǣ and Mercian ē, and the final *-i was lost after the heavy syllable: West Saxon has dǣd, Mercian and Anglian dēd.[1][2] In Old Dutch, the Old Low Franconian psalms have the accusative plural deda,[10] and Williram's commentary of about 1100 has daaden.[11]

Meanings

  1. deed[2][3]

Old Frisian also used the word for "crime",[1] and for "wound";[12] Old Saxon also for "event, power, omen",[9] and Old High German for "action, event, thing".[13]

Derivatives

  • *balwadādi "misdeed, evil deed", which Wiktionary reconstructs and takes for a possible calque of Latin maleficium;[14] Old Saxon has the compound baludād.[9]
  • *firinudādi "wicked deed, crime", which Wiktionary reconstructs;[15] Old English, Old Saxon and Old High German have the compound.[16][9][17]
  • Wiktionary reconstructs Proto-Germanic *missadēdiz (“misdeed”);[18] Orel lists the compound in Old English, Old Saxon and Old High German.[19]

Reflexes

  • Old English: dǣd (“deed, action, event”)[20]
  • Old Frisian: dēde (“deed, act, wound, crime”)[12]
  • Old Saxon: dād (“deed”)[21]
  • Old Dutch: dāt (“deed”)[11]
  • Old High German: tāt (“deed, action, event, thing”)[13]
