Etymology

It is inherited from Proto-Italic *moks, inherited from Proto-Indo-European *moḱs (“soon”).[2][1][3] De Vaan leaves open whether the PIE word was a locative plural in ⟨*-su⟩ or a u-stem, and calls the root uncertain.[2]

Cognate with Old Irish mos- (“soon”), Middle Welsh moch (“soon”), Sanskrit मक्षू (makṣū́, “quickly”) and Avestan mošu (“soon”).[2][4][5]

Earliest recorded meaning

De Vaan dates it from Plautus;[2] in the prologue of the Menaechmi the speaker warns nē mox errētis, “so that you do not go wrong soon”.[4] Köbler cites it first from Ennius.[3]

Semantic evolution

Mox is “soon, presently”, of the near future;[4][6] quam mox? asks “how soon?”.[4][6] Of the past it means “a little later, afterwards”, and in lists “next”, in place or in rank.[4] The jurists use mox quam for “as soon as”.[4]

In Medieval Latin it means “at once”, and as a conjunction (mox ut or mox alone) “as soon as”.[7]

Timeline

  • c. 250–184 BC – Plautus: nē mox errētis.[4][3]
  • 190–159 BC – Terence: mox ego hūc revertor, “I'll be back here soon”.[6][3]
  • 70–19 BC – Virgil uses it for “afterwards, next”.[4][3]
  • 23/24–79 AD – Pliny the Elder uses it for the next item in a list.[4][3]
