Etymology

From Proto-Italic *izdim; equivalent to is (“he”) + Proto-Italic *-im (emphatic marker) (whence Sabellic *-om, Oscan 𐌝𐌔𐌝𐌃𐌖𐌌 (ísídum), 𐌄𐌔𐌝𐌃𐌖𐌌 (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 eōd, eād became eō, eā, the true forms eōd-em, eād-em were interpreted as eō-dem, eā-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, ibīdem, etc. Compare tam-en with its later doublet: tan-dem (← *tam-dem).

Pronunciation

• (Classical) IPA^(key): /ˈiː.dem/, [ˈiːd̪ɛ̃ˑ]
• (Ecclesiastical) IPA^(key): /ˈi.dem/, [ˈiːd̪em]

Pronoun

īdem (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 īdem

     Love is the same for all

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 /iː(s)/, with later remodelling - compare the etymology of deus. This /iː/ was normally spelled as EI during and as II after the Republic; a disyllabic iī, spelled II, Iꟾ, apears in Silver Age poetry, while disyllabic eīs is only post-Classical. Other spellings include EEI(S), EIEI(S), IEI(S).
²The dat. singular is found spelled EIEI (here represented as ēī) 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.
