Things we can say about nouns
Introduction
Part II The parts of speech

At the risk of offending some scholars, it seems pedantic to insist on the retention of Latin and Greek plurals for common words which are clearly now part of our language, just as many words absorbed from other languages over past centuries now conform to English usage.

It seems therefore logical that the plural of curriculum and syllabus should be curriculums and syllabuses. But both forms are acceptable and should not be corrected.

Greek and Latin for medical, botanical and other scientific terms is favoured and the unscholarly person’s answer to this is to come up with everyday readily recognisable names, such as dove (Greek ptilinopus) and daylily (Hermerocallis).
