The phonetic transcription is /æθˈrɛpsiə/, with stress on the second syllable. The "th" is pronounced as in "thin", the "r" sound is slightly rolled or tapped, and the "ps" is pronounced together as in the word "lips". The word is commonly used in medical terminology to describe a condition of malnutrition or wasting away of the body.
1. Innutrition; specifically, marasmus of the newborn. 2. Immunity to inoculation of tumor cells, assumed by Ehrlich to be due to the absence of the special nutritive substance upon which the growth of tumors was supposed by him to depend.
