catchword n.1730, "the first word of the following page inserted at the lower right-hand corner of each page of a book," as a guide to the binders, from catch (v.) + word (n.); extended to "word caught up and repeated" (especially in the political sense) by 1795. The thing in the literal sense is extinct; the figurative sense thrives. updated on November 13, 2022 |
