If there is less inflammation, the cholesteatoma may present the appearance of 'semolina' discharging from a defect in the tympanic membrane. The posterior and superior parts of the tympanic membrane are most commonly affected.
Common name or coinages; such names generally are difficult for laymen to learn, remember, and pronounce and so, in such books as field guides, biologists commonly publish lists of coined common names. Many examples of such common names simply are attempts to translate the Latinised name into English or some other vernacular. Such translation may be confusing in itself, or confusingly inaccurate, for example, "gratiosus" does not mean "gracile" and "gracilis" does not mean "graceful". The practice of coining common names has long been discouraged; de Candolle's "Laws of Botanical Nomenclature", 1868, the non-binding recommendations that form the basis of the modern
