Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

sumptio (collat. form sumpsio, Cato, R. R. 145, 2), ōnis, f. [sumo], a taking.

  1. I. Lit., Vitr. 1, 2, 2.
  2. II. Trop., in logic, a premise taken for granted, an assumption: demus tibi istas duas sumptiones, ea quae λήμματα appellant dialectici; sed nos Latine loqui malumus, Cic. Div. 2, 53, 108.
