Etymology

From Proto-Italic *izdim; equivalent to is (“he”) + Proto-Italic *-im (emphatic marker) (whence Sabellic *-om, Oscan ???????????????????????? (ísídum), ???????????????????????? (esídum)), from Proto-Indo-European *im (whence also Old Latin im, em), accusative singular of *éy (so both parts are from the same source). The s was lost and the i lengthened by compensatory lengthening.

When the ablative cases e?d, e?d became e?, e?, the true forms e?d-em, e?d-em were interpreted as e?-dem, e?-dem. The neuter nominative singular id-em is natural and gives earlier emem (= later eundem). The new marker -dem then served to create totidem, tantumdem, ib?dem, etc. Compare tam-en with its later doublet: tan-dem (? *tam-dem).

Pronunciation

• (Classical) IPA^(key): /?i?.dem/, [?i?d????]
• (Ecclesiastical) IPA^(key): /?i.dem/, [?i?d??m]

Determiner

?dem (feminine eadem, neuter idem); demonstrative pronoun (with m optionally ? n in compounds) with an indeclinable portion

1. the same
   • 29 bc. Virgil. Georgics, III

     amor omnibus ?dem

Declension

Irregular declension. Similar to the declension of is, ea, id.Demonstrative pronoun (with m optionally ? n in compounds) with an indeclinable portion.

¹The nom./dat./abl. plural forms regularly developed into a monosyllable /i?(s)/, with later remodelling - compare the etymology of deus. This /i?/ was normally spelled as EI during and as II after the Republic; a disyllabic i?, spelled II, I?, apears in Silver Age poetry, while disyllabic e?s is only post-Classical. Other spellings include EEI(S), EIEI(S), IEI(S).
²The dat. singular is found spelled EIEI (here represented as ??) and scanned as two longs in Plautus, but also as a monosyllable. The latter is its normal scansion in Classical. Other spellings include EEI, IEI.
