gingerbread

From Middle English gyngebred, gyngebrede, from Old French gingembras, gingimbrat (“preserved ginger”), from Medieval Latin *gingimbrātus (“gingered”, presumably referring to ginger that perhaps had a pharmaceutical use for some medicinal preparation), with the intrusive m added to gingiber, from Latin zingiber (“ginger”), of earlier Sanskrit origin, through Ancient Greek ζιγγίβερις (zingíberis). The third syllable was earlier confounded with bread, and the insertion of an r in the second syllable completed the semblance of a compound word: ginger + bread.
