It’s first appearance in print was in the London Sunday Times on February 25, 1959. “We are pretty sure that all Sunday Times readers are natural and inveterate logophiles.”
Here are a few examples of use:
“How serendipitous is that, since I am both a blogophile and a logophile?”
“There probably isn't a better gift for a logophile or linguist than witticisms and wordplay - the clever kind or the chocolate version of such.”
