<Tina Tang (language evolution researcher)> coauthored the 2007 study relating historical changes in English irregular verbs to <word frequency>. Its byline identifies the author with Harvard's Program for Evolutionary Dynamics.<Quantifying the evolutionary dynamics of language by Erez Lieberman and others>[Byline and affiliations]{ref}
The authors found an approximate square-root relation between frequency and irregular-verb <half-life>. A hundredfold increase in frequency corresponds to a tenfold increase in half-life under that fitted relation. It describes a statistical pattern across the studied verbs, rather than a schedule for when an individual verb must change.<Quantifying the evolutionary dynamics of language by Erez Lieberman and others>[Figures 1–2]{ref}
