Pronunciation

  • Classical: [ˈsɪ.kʷɪ.dẽː][1]
  • Ecclesiastical: [ˈsiː.kʷi.dem][1]

Forms

siquidem (not comparable)[1] It is also written separately, sī quidem.[2][3] Plautus has the old spelling seiquidem.[2] The first syllable is often short in comedy and regularly in dactylic verse.[2][3]

Etymology

It is from Latin sī (“if”) + quidem (“indeed”), written as one word.[2][1]

Earliest recorded meaning

The OLD's first examples are in Plautus, as in the Poenulus: “if friendship is really to be had, it must be had with this man”.[2] Köbler dates it from Cicero.[4]

Semantic evolution

It begins as a strong conditional, if indeed, if it is really the case that, and as a concessive, even supposing, as Plautus' “even if you say you have held back highest Jupiter himself, you will never escape a beating”.[2] It adds a caveat or rider, at any rate if, and in dialogue qualifies another's remark: “good day, young man” – “yes, if I sell her at her price”.[2] From there it becomes causal, seeing that, since, as in Plautus' “it must be borne, since my wife holds command”, and explanatory, in that, for.[2][3] Church Latin glosses it if, indeed, for, because, since,[5] and in Medieval Latin it is used like autem, further.[6][1]

Timeline

  • c. 250–184 BC – Plautus as a conditional and causal particle.[2][4]
  • 190–159 BC – Terence of “if indeed”.[3][4]
  • 81–43 BC – Cicero uses it.[4][3]

  4. In that, for.[2]
