The vocabulary used by Anthony Burgess in his books is among the largest of any modern author. He is fond of extremely unusual words, some of which are obsolete. He uses descriptive forms of words that are normally seen as nouns, or vice versa, and he employs jargon from technical or semi-technical pursuits, such as music, rhetoric, or biology. Examples of such words in this novel, which are not included in the vocabulary section of this guide because of their highly unusual nature, include: steatopygous, tigrine, alveolizing, strabismus, vexillae, chunnering, bathycolpous, flavicomous, spondees, celidhs, anthropophagy, and thallasographers.
