Luwian word of the day: ipatarmayan (probably meaning "westward").   
 Probably from the root *(h₃)yebʰ-, which originally meant "enter" (here in reference to the sun, entering in the west) but received... a more specific (and sexual) meaning in the Indo-European branches outside Anatolian and Tocharian. This change in meaning is, btw, one of the arguments often adduced for Anatolian and Tocharian being the two earliest to leave the common IE fold (among numerous others). Also, this happens to be a photo from West Road in Cambridge!I guess that could be something like iparwaššiš ḫar(u)waš ("western road") in Cuneiform Luwian (in the nominative singular)!
