The plural nominative is iidem or eidem, eaedem, eadem. In the genitive plural the m also becomes n: eorundem, earundem. Use idem with a noun (idem puer) or on its own (idem dicit).

To say the same as, use idem qui (the same person who) or idem atque (the same as): Idem sentio atque tu. The word after atque is in the same case as the thing compared.

Examples (5)

  1. Marcus idem dicit.

    Marcus says the same thing.

    Idem is the neuter accusative singular, the object of dicit.

  2. Eadem puella semper in horto sedet.

    The same girl always sits in the garden.

    Eadem is feminine nominative singular, to agree with puella.

  3. Idem sentio atque tu.

    I think the same as you.

    Idem atque means the same as. Tu is nominative, like the I of sentio.

  4. Eodem die Marcus Iuliam vidit.

    On the same day Marcus saw Iulia.

    Eodem die is the ablative of time when. Eodem agrees with die.

  5. Tu autem idem ipse es, et anni tui non deficient.

    But you are the same, and your years will not end.

    Psalm 101:28. Idem ipse es means you are the very same one. Idem and ipse are both nominative singular.

Common Mistakes

  • Not matching idem to its noun.

    Idem puella in horto sedet.
    Eadem puella in horto sedet.

    Idem agrees with its noun like any adjective. Puella is feminine, so the form is eadem.
