Final answer:
The stem 'febri' in the word afebrile means 'lack of fever' or 'without fever', and it is used in medical contexts to describe a patient's normal temperature status.
Step-by-step explanation:
The stem 'febri' in the word afebrile means 'lack of fever' or 'without fever.' When someone is afebrile, they do not have a fever. This term is commonly used in medical settings to describe a patient's condition. For example, a patient recovering from an infection might be described as afebrile if their temperature has normalized.
Understanding the meaning of the prefix 'a-' is also important, as it denotes the absence of something. In this case, 'a-' combined with 'febri' specifically indicates the absence of fever.
