What does -philic mean?

The combining form -philic is used like a suffix to indicate the adjective form of words that use the form -phile, meaning “love or liking,” “unnatural attraction,” or “tendency.”

The form -philic roughly means “characterized by a liking, tendency, or attraction.” In scientific terms, -philic is specifically used to label groups of organisms with a particular affinity for an environment, substance, or other element. It is frequently used in scientific and everyday terms, especially in biology.

The form -philic is made from a combination of two combining forms. The first is -phile, from Greek phílos, meaning “dear, beloved.” The second form is the suffix -ic. The suffix -ic ultimately comes from Greek -ikos, which was an ending used to form adjectives.

While -philic doesn’t have any variants, it is related to six other combining forms: -phile, -philia, -philiac, -philism, -philous, and -phily. Want to know more? Check out our Words that Use articles for each form.
