poecilonymy

Noun

poecilonymy (uncountable)

1. The use of several names for the same thing in the same document.
   • Stated in technical linguistic terms, in this treatise poecilonymy is avoided; e. g., instead of taenia hippocampi in one place, corpus fimbriatum in another, and fimbria in a third, the last is consistently employed and the others given as synonyms.1890, Univ. of Pennsylvania Medical Bulletin: Volume I-XXIII
   • There are also too many relapses into poecilonymy; for example, on p. 758 occur appendix vermiformis, appendix, and rermiform appendix, whereas on p. 160 had already been introduced, without explanation, the very convenient contraction of the third term into vermix.1893, The Nation - Volume 56, page 850
