Ultimate origin
Proto-Indo-European (*m(i̯)euh₁-)

Pronunciation

  • Classical: [ɪmˈmoː.tʊs][1]
  • Ecclesiastical: [imˈmɔː.tus][1]

Forms

immōtus (feminine immōta, neuter immōtum); first/second-declension adjective[1] It is also spelled inmōtus;[2][3] Priscian teaches that it should be written with im-.[4]

Etymology

It is formed from the negative prefix in- (“not, un-”) and mōtus (“moved”), the participle of moveō (“to move”).[2][3][4] ⟨moveō⟩ goes back to Proto-Italic *mow(a)- and Proto-Indo-European *m(i̯)euh₁- (“to move”), cognate with Hittite mau- (“to fall”) and Sanskrit मीवन्ती (-mī́vantī, “pushing down”).[5] The TLL compares the Greek negative adjective ἀκίνητος (akínētos, “unmoved”).[4]

Earliest recorded meaning

Köbler gives Virgil as its first author;[6] in the Aeneid the Sibyl's leaves stay unmoved in their places and do not leave their order.[2]

Semantic evolution

It is not moved or motionless, as Virgil's tree that stands unmoved, and of a harbour or the sea undisturbed and calm, as Virgil's harbour sheltered from the winds.[2][3] Of abstract things it is unchanged or fixed, as Virgil's “the fates of your people remain unchanged”, and in Velleius of a state where nothing was left undisturbed.[2] Of feelings it is unmoved, unrelenting or inflexible, as Ovid's ears deaf to the lowing of the victim.[2][3]

Lewis and Short call it mostly poetic and post-Augustan.[3] Church Latin glosses it “unmoved, unchanged, steadfast”.[7]

Timeline

  • 70–19 BC – Virgil of motionless leaves and of unchanging fates.[2][6]
  • 43 BC–18 AD – Ovid of ears unmoved by entreaty.[2][6]
