For example, earlier you learned that the root word algesia means sensitivity to pain. When used in combination with hypo, the word becomes hypalgesia, without the letter o. In other cases, the o is retained, such as with the root word esthesia. In this case, the resulting word is hypoesthesia. Slide 7 of 10
