Q. The author wishes to have first mention of foreign words italicized and explained. The book consists of a series of weekly readings, and therefore the reader may well not start at the beginning. In these circumstances, should the first mention of a foreign word in each article be italicized and explained, even though there will be many duplications throughout the book?
A. You could do it that way, but readers might lose interest after a certain amount of repetition. It would be better to have a glossary in the back of the book.
