Residue may refer to:

  • Residue (chemistry), material remaining after a distillation or an evaporation, or portion of a larger molecule
    • In particular, in biology, often refers specifically to an amino acid
  • Residue (law), portion of the testator's estate that is not specifically devised to someone in the will
  • Residue (complex analysis), complex number describing the behavior of line integrals of a meromorphic function around a singularity
  • Residue (partial fraction decomposition), the numerator of the expanded terms
  • Crop residue, materials left after agricultural processes
  • Relationship residue, lingering feelings occurring after the commencement of a relationship often brought about by the unwillingness of one party to let go which can lead to sporadic emotional discharges.

Residue may also be:

  • The remainder in modular arithmetic
  • The heavier fractions of crude oil that fail to vaporize in an oil refinery

Famous quotes containing the word residue:

    Every poem of value must have a residue [of language].... It cannot be exhausted because our lives are not long enough to do so. Indeed, in the greatest poetry, the residue may seem to increase as our experience increases—that is, as we become more sensitive to the particular ignitions in its language. We return to a poem not because of its symbolic [or sociological] value, but because of the waste, or subversion, or difficulty, or consolation of its provision.
