Reconstruction

The word is *dēdiz in Ringe and Wiktionary,[1][2] *đēđiz in Orel,[3] and the stem *dēdi- in Kroonen and Köbler,[4][5] who also gives *dǣdi-.[5] Fulk writes *dē-ðí-.[6]

Etymology

It is inherited from Proto-Indo-European *dʰéh₁tis (“act of putting”), through an intermediate *dʰētís with the accent on the suffix.[1][2] Kroonen calls it a ti-stem derived from the root *dʰeh₁- of *dōną.[4] Wiktionary also sets up a homonymous adjective *dēdiz "doing, able to do, active", a verbal adjective to the verb.[2]

Morphology

A feminine i-stem,[5] which Kroonen calls a ti-stem;[4] Wiktionary analyses it as *dōną with the suffix *-þiz.[2] Ringe takes it as a fossil of the proterokinetic ti-stems of Proto-Indo-European: it has a full-grade root but, judging from the voiced Verner's law variant of its suffix, an accent on the end.[7]

Evidence

The word is attested in all three branches: Gothic 𐌲𐌰𐌳𐌴𐌸𐍃 (gadēþs) in Gothic, Old Norse dáð in Old Norse, and Old English dǣd, Old Frisian dēde, Old Saxon dād and Old High German tāt in West Germanic.[3] The Gothic noun occurs only in compounds,[8] such as 𐌼𐌹𐍃𐍃𐌰𐌳𐌴𐌸𐍃 (missadēþs, “misdeed, sin”).[1] Old Norse has the noun but not the verb it belongs to.[9]

Competing analyses

Orel finds the formation identical with Lithuanian dėtis (“load”), from IE *dhē- "to put, to set".[3] Ringe compares Ancient Greek θέσις (thésis).[1]

Meanings

  1. deed, action[4][5][2]

Old Norse also used the word for "good quality",[9] Old Frisian for "wound" and "crime",[10] and Old Saxon for "event", "power" and "omen".[11]

Derivatives

  • *missadēdiz "misdeed",[12] Orel's *missa-đēđiz.[13]
  • *weladēdiz "good deed, benefit",[14] Orel's *wela-đēđiz.[15]
  • *wai-đēđiz "evil deed".[16]
  • *-dēd-ijan-, a n-stem in Gothic 𐍅𐌰𐌹𐌳𐌴𐌳𐌾𐌰 (waidedja, “robber”).[17]
