pseunonymous
 adj.— «Known only by the false name of Mark Brown, he became a “pseunonymous” witness—a phrase coined at the start of the trial. The jury, barristers and the judge all heard his real voice from the witness stand but a distorted voice was fed into the soundproof defendants’ dock and into a separate annex court room where the public gallery and the press were stationed.» —“Murder trial sets legal precedent” BBC News Mar. 18, 2005.
