\Pur"ism\, n. [Cf. F. purisme.]
Rigid purity; the quality of being affectedly pure or nice,
especially in the choice of language; over-solicitude as to
purity. ``His political purism.'' --De Quincey.
      The English language, however, . . . had even already
      become too thoroughly and essentially a mixed tongue
      for his doctrine of purism to be admitted to the
      letter.                                  --Craik.
