pathologic

The word "pathologic" is built from Greek components that literally mean "pertaining to the study of disease." The root pathos carried a broad sense of suffering or experience in ancient Greek, which narrowed in medical terminology to specifically denote disease. Combined with -logia (the study of), it formed the basis for "pathology." The adjectival suffix -ic was then attached, a common pattern in scientific English borrowed via Latin. Thus, the term evolved from a literal descriptor of a field of study to an adjective characterizing any phenomenon directly caused by or indicative of disease, reflecting a shift from the process of study to the inherent qualities of the subject itself.

Structure: patho (disease) + log (study) + ic (adjective suffix) - patho: From Greek pathos, meaning "suffering, disease, feeling." In this word, it functions as a root denoting disease. - log: From Greek -logia, from logos meaning "word, reason, study." In this word, it is a combining form meaning "the study of." - ic: A suffix from Latin -icus and Greek -ikos, used to form adjectives meaning "of, pertaining to, or characteristic of."
