Next up, "weak" and "broken". ("Lame duck" anyone?) When the OED includes the "modern" non-physically-impaired definition (in use since the 1600s at least), and with the use of "lame" in the physically-impaired sense on the decline, I'm not sure this is the best target. Anecdotally, when I worked with "disabled" people, they used it all the time, in the modern sense. They would have been taken aback had anyone used the term to describe their disabilities/infirmities. (Full disclosure: This isn't a word I use often anyway.) Good luck!
