nempe

Nempe is a particle of confirmation, and its tone depends entirely on who is speaking. In argument it means "obviously, as we both know perfectly well" and is often faintly needling - the Latin for "well, quite". In exposition it means "namely, that is to say", introducing the item the previous phrase was pointing at, and there it does the same job as scilicet and videlicet.

It stands early in its clause and demands no particular mood. Roman comedy uses it to score points off the other speaker; philosophy and theology use it to itemise. Reading Plautus with a scholastic face, or Boethius with a comic one, will misjudge half the sentences it appears in. Compare enim, which gives a reason, and quidem, which concedes; nempe does neither, it asserts what it claims is already agreed.
