The full Latin term is _milia passum_, literally 'a thousand of steps', i.e. of a military unit on march. I wonder if _mil_ as a Persian unit of measurement isn't spurious, or in fact a Greek (or e.g. Phrygian) word since Old Persian did not have any /l/ sound. At least in the OP script PIE _*l_ has merged totally with _*r_. In Middle Persian OP _rd_ became _l_. Possibly that happened early in the spoken language. /Benct > Best regards: Otared > > > > > ___________________________________________________________________________________ > If your question is of interest to others as well, please add an entry to > the Wiki! > > maillist : ntg-context@ntg.nl / > http://www.ntg.nl/mailman/listinfo/ntg-context > webpage : http://www.pragma-ade.nl / http://context.aanhet.net > archive : https://bitbucket.org/phg/context-mirror/commits/ > wiki : http://contextgarden.net > > ___________________________________________________________________________________ >
