Dear Mark,
I look for Swadesh lists at www.rosettaproject.org . There are 2 lists there for Latin, but I can't view them with my home browser.
I'm rather sceptical of Swadesh lists for reconstructed languages. How do we know we have the _usual_ word for a meaning? For example, is PIE for 'red' *h1rudHro- or *h1reudH- ?
