The spelling of the word "dihysteria" can be explained using the International Phonetic Alphabet (IPA) phonetic transcription. The first two letters "di" represent the prefix meaning "two." The next four letters "hys" represent the root word "hyster," referring to the uterus. The following letter "t" is the interfix, meaning it connects two parts of a word. The final two letters "eria" represent the suffix meaning "disease or abnormal condition." Therefore, "dihysteria" refers to a condition involving two uteri.
A condition in which there is a double uterus.
