Pseudo means not authentic, false, pretend. Pseudo may also mean having a close resemblance to. The word pseudo is often used with another word, hyphenated, to refer to something that is inauthentic, such as pseudo-science or pseudo-intellectual. Pseudo- is also a prefix used in words such as pseudonym. Pseudo comes to us in the late fourteenth century to mean something false or spurious, from the Greek word pseudes meaning false and the Greek word pseudein meaning to lie. Popularity of the word pseudo and the prefix pseudo- has steadily risen over the last two centuries, according to Ngram, its use nearly doubling between 1900 and 1960.
