WORDS THAT USE -DERMIS

What does -dermis mean?

The combining form -dermis is used like a suffix meaning “skin” or “layer of tissue.” It is used in a number of scientific terms, especially in botany and zoology.

This form is directly based on epidermis, the thin outer layer of the skin, from the Greek epidermís, “surface skin” (more on this word in the next section below).

The word dermis was extracted from epidermis and refers to the dense inner layer of skin. All of these words ultimately come from the Greek dérma, meaning “skin.”

The Greek dérma also helps form the word taxidermy. Discover more about its roots in our entry for the word.

Closely related to -dermis are the combining forms -derm, -derma, -dermatous, dermat-, dermato-, derm-, and dermo-. Learn their specific applications in our Words That Use articles for these forms.

The first portion of the word, epi-, means “upon” or “over,” among other senses. The second part of the word, -dermis, refers to “skin.” So, epidermis has a literal sense of “upper skin.”
