Origin

from Greek pseudēs false, from pseudein to lie

Synonyms

= false, pretended, artificial, fake, phoney or phony, mock, imitation, bogus, sham, counterfeit, spurious, ersatz, not genuine, quasi-,

pseudo-

often before vowels pseud-, word-forming element meaning "false; feigned; erroneous; in appearance only; resembling," from Greek pseudo-, comb. form of pseudes "false, lying; falsely; deceived," or pseudos "falsehood, untruth, a lie," both from pseudein "to deceive, cheat by lies."

Productive in compound formation in ancient Greek (such as pseudodidaskalos "false teacher," pseudokyon "a sham cynic," pseudologia "a false speech," pseudoparthenos "pretended virgin"), it began to be used with native words in Middle English.
