The Locative Case (p1)

My last post left me curious about the precise use and character of the Locative case, so I took to milling around A&G for just about every line I could find on the matter. There’s more than the might imagine for a case so rare–

Let’s start with the formation of the locative case (post 1) and then I’ll search out all the things we can do with it (post 2).


Formation for First Declension

singular genitive; plural dative

(Rōmae; Athēnīs)

[remember that only place names which are already plural, like Athēnae, will appear with a plural locative]


Formation for Second Declension

singular genitive; plural dative

[Corinthī; Philippīs]


Formation for Third Declension

singular dative or ablative (-ī or -e); plural dative

[Carthāginī or Carthāgine; Trallibus]


Formation for Fourth Declension

The only locative offered by A&G is that for domus, house: it’s either domī or domuī


Formation of the Fifth Declension

Here, the locative only appears in a few fixed expressions of time, where it always ends in the singular ablative:

hodiē, today; diē quārtō (etc.), on the fourth day; postrīdiē, tomorrow; perendiē, the day after tomorrow; prīdiē, yesterday


1 —> gen/dat; 2 —> gen/dat; 3 —> dat or abl/dat; 4&5 —> just a few words!


The Essential AG: (scattered, I know) 43c; 49a; 80; 93 n1; 98b

Famous Phrase: in locō parentis [in place the parent]

This is a legal term describing a state of non-parent custody of children; a teacher or your aunt (while you’re staying at her cottage) are in locō parentis figures


One comment on “The Locative Case (p1)

  1. Jim Bryan says:

    It is easier to think that “i” is the sign of the locative
    First declensions was originally “ai” but later all “ai” became “ae”s
    “i” works for the singular of all declensions except the fourth declension

    First originally ai all ai become ae in Latin
    Romae (originally Romai)
    Melitiae in service, at woar

    Corinthi Corinthus
    Ephesi Ephesus
    Londinii Londinium

    Belli at war bellum
    Humi on the ground (humus)

    ruri in the country rus rusis
    Neapoli Neapolis is
    Eo Tempuri at that time (tempus temporis)
    Vesperi at evening (vesper, vesperis) (or vespere)

    4th domi at home Domus, domus
    Animi in mind (animus, animus)

    Ubi where
    Hic (hi +ce) here
    Istic isti +ce there by you
    Illic illi +ce over there
