Dr. Louise Pound 49 notes that a number of Latin plurals tend to become singular nouns in colloquial American, notably curricula, data, dicta, insignia and strata, and with them a few Greek plurals, e. g., criteria and phenomena. She reports hearing the following uses of them: “The curricula of the institution is being changed,” “This data is very significant,” “The dicta, ‘Go West,’ is said to have come from Horace Greeley,” “What is that insignia on his sleeve?”, “This may be called the Renaissance strata of loan-words,” “That is no criteria,” and “What a strange phenomena!”—all by speakers presumed to be of some education. The error leads to the creation of double plurals, e. g., curriculas, insignias, stratas, stimulis, alumnis, bacillis, narcissis. The Latin names of plants lead to frequent blunders. Cosmos and gladiolus are felt to be plurals, and from them, by folk-etymology, come the false singulars, cosma and gladiola. Dr. Pound notes many other barbarous plurals, not mentioned above, e. g., antennas, cerebras, alumnas, alumnuses, narcissuses, apparatuses, emporiums, opuses, criterions, amœbas, cactuses, phenomenons. |
