Morphology

mucosa = mucus (semi-transparent) = mucos + a

The word clearly refers to tissue related to mucus, but its formation uses a Latin technical noun ending ('-a') that is not a productive English suffix, making it a specialized borrowing.

Etymology

Mucosa comes from the Latin mucus, meaning 'mucus', plus the ending -osa, meaning 'full of'. So a mucosa is the body lining 'full of mucus' that helps protect and keep places like the mouth, nose, and gut moist.
