Forms
þat pron n (genitive þess, dative því or þí), the neuter singular of sá, whose masculine and feminine nominatives come from another stem.[1]
Etymology
It is inherited from Proto-Germanic *þat (“that”), the neuter of *sa (“that”),[2] from Proto-Indo-European *tód, the neuter of *só.[2] Its West and East Germanic counterparts are Gothic 𐌸𐌰𐍄𐌰 (þata), Old English þæt, Old Frisian thet, Old Saxon that and Old High German daz.[3][4] The Gothic form has an extra final vowel that Orel calls unclear, perhaps a particle.[3]
Ásgeir Blöndal Magnússon reconstructs the Germanic form as *þata and the Indo-European one as *tod, and places the word in the pronominal stem *to-, *te-, together with Ancient Greek τό (tó) and the second part of Latin istud.[5] De Vries gives the same comparisons.[4] Köbler traces the stem to Pokorny's root Proto-Indo-European *to-.[6]
The same stem gives the rest of the paradigm of sá except its masculine and feminine nominative singular, and also þar, þaðan and þeir.[5][1]
Earliest recorded meaning
The record dates the pronoun first in the Icelandic First Grammatical Treatise, which IcePaHC dates to 1150.[7] Menota's lemmatised texts have it in the fragment Lbs fragm. 82, of 1258–1264.[8] Cleasby and Vigfússon note that the demonstrative use “this, these” is frequent on runic stones.[1]
Semantic evolution
Old Norse used the word both as the neuter of the demonstrative sá and as the neuter of the personal pronoun hann, meaning “it”.[5][1] As a personal pronoun it was the empty subject of phrases like þat var einhverju sinni, at “it happened once that”.[9] It often refers back to a masculine or feminine noun, and it can stand before a plural verb as “they”.[10] From the pronoun came an adverbial use, so, to that degree,[9][11] and use as a conjunction that, in place of at.[9][12]
Modern Icelandic writes it það,[5] and the mainland languages have Norwegian Bokmål det, Swedish det and Danish det.[4]
