Don't remember them teaching me about these in logic class.

   2. The use of a strained figure of speech, such as a mixed metaphor.

hy ·poc ·o ·rism

   1.    a pet name.
   2.    the practice of using a pet name.
   3.    the use of forms of speech imitative of baby talk, esp. by an adult.

me ·ton ·y ·my

   1.   A figure of speech in which one word or phrase is substituted for another with which it is closely associated, as in the use

   2.  In schizophrenia, a language disturbance in which an inappropriate but related word is used in place of the correct one.

syn ·ec ·do ·che

    A figure of speech in which a part is used for the whole (as hand for sailor), the whole for a part (as the law for police officer), the specific for the general (as cutthroat for assassin), the general for the specific (as thief for pickpocket), or the material for the thing made from it (as steel for sword).
