What does the suffix "-ical" signify in medical terminology?

The suffix "-ical" is commonly used in medical terminology to denote a relationship or connection to a certain subject or field. When attached to a root word, it indicates that something is "pertaining to" that subject. For example, in the term "medical," the suffix suggests that the subject is related to medicine. By using this suffix, medical professionals create terms that specify the context or field to which they are referring, allowing for precise communication within the healthcare environment. This understanding is crucial for anyone engaged in medical studies or practices, as it enhances clarity in the language used to describe various aspects of health and medicine.
