Morphology

pseudomembranous = membranous (transparent) = pseudo + membran + ous

The word is formed by adding pseudo- to membranous, giving the clear sense of 'false membrane-like'.

Etymology

Pseudomembranous breaks into pseudo- meaning 'false' and membrane meaning 'a thin layer or skin'. So, pseudomembranous describes tissue that has a 'false' membrane — a layer that looks like a real covering but is not, often forming because of infection.
