       A grammatical figure (figura constructionis) is one that depends 
        upon some manipulation of specific grammatical elements, or which purposefully 
        alters normal grammatical conventions for effect. Grammatically based 
        figures are often simply the purposeful or artistic use of grammatical 
        vices. 
      This classification of figures has by no means been universal over time. 
        The following list is a synthesis.

       Many grammatical figures are syntactical, relying upon some arrangement, 
        manipulation, or emphasis of syntax. These are in fact grammatical 
        schemes. 
       
       
        - anacolouthon
 
          A grammatical interruption or lack of implied sequence within a sentence. 
        - anapodoton
 
          A figure in which a main clause is suggested by the introduction of 
          a subordinate clause, but that main clause never occurs.  
        - asyndeton
 
          The omission of conjunctions between clauses, often resulting in a hurried 
          rhythm or vehement effect.  
        - polysyndeton
 
          Employing many conjunctions between clauses, often slowing the tempo 
          or rhythm.  
        - hyperbaton
 
          An inversion of normal word order. 
        -  zeugma 
 
          A general term describing when one part of speech (most often the main 
          verb, but sometimes a noun) governs two or more other parts of a sentence 
          (often in a series) 
         -  syllepsis 
 
          When a single word that governs or modifies two or more others must 
          be understood differently with respect to each of those words. 
         -  appositio 
 
          Addition of an adjacent, coordinate, explanatory or descriptive element. 
        
      
      Some grammatical figures depend upon some sort of grammatical substitution: 
       
       
       
        - enallage 
 
          The substitution of grammatically different but semantically equivalent 
          constructions. 
         - antiptosis 
 
          A type of enallage in which one grammatical case is substituted for 
          another. 
        
      
      Some grammatical figures may in fact be errors or vices (or the 
        purposeful use of these): 
      
        - solecismus 
 
          An element of speech or writing that is incorrect grammatically. 
         - synchysis 
 
          The confused arrangement of words in a sentence; hyperbaton or anastrophe 
          taken to an obscuring extreme, either accidentally or purposefully.
