• eidem (frequently in manuscripts and inscriptions)
• isdem, eisdem (rarely)^[1]
• ide (Late Latin, proscribed)

From Proto-Italic *izdim; equivalent to is ("he") + Proto-Italic *-im (emphatic marker) (whence Sabellic *-om, Oscan (isidum), (esidum)), from Proto-Indo-European *im (whence also Old Latin im, em), accusative singular of *ey (so both parts are from the same source). The s was lost and the i lengthened by compensatory lengthening.^[2]

When is' ablative cases eod, ead became eo, ea, idem's ablative true forms eod-em, ead-em were interpreted as eo-dem, ea-dem. The neuter nominative singular id-em is natural. De verborum significatione gives emem as a form of the later eundem.[1] The new marker -dem then served to create totidem, tantundem, ibidem, etc. Compare tam-en with its later doublet: tan-dem (- *tam-dem).

• (Classical Latin) IPA^(key): ['i:.de:], ['I.de:]
• (modern Italianate Ecclesiastical) IPA^(key): ['i:.dem]

idem (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 idem

     Love is the same for all

   • 29 BCE - 19 BCE, Virgil, Aeneid 4.678-679:

     "[...] Eadem me ad fata vocasses:
     idem ambas ferro dolor, atque eadem hora tulisset."

     "You should have called me to the same fate: Both of us could have been taken by the sword - the same pain, and at the same hour."
     (Anna speaks to her dying sister, Dido.)

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 ii, spelled II, I, appears in Silver Age poetry, while disyllabic eis is only post-Classical. Other spellings include EEI(S), EIEI(S), IEI(S).
²The dat. singular is found spelled EIEI (here represented as ei) 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.
