upsila

noun

1. (form-of, plural)plural of upsilon

   “Why there is no parallel ḫi- remains a mystery. It is idle to argue for some kind of parasitic origin, comparable to the rampage of spiritus asper over initial upsila in Attic Greek; the very contrast ḫu- : w- is distinctive.”

   “Gk. ῦει ‘to rain’ may represent either *sE₂uH₂-ye- or *E₂uH₂-ye- (spiritus asper being automatic on initial upsila), thus a -ye/o- derivative (stative like e. g. χαίρω?) from the zero grade of the root stem seen in Toch. A 3 pl. swiñc < *sE₂uH₂-énti.”

   “Serifs are a regular feature of letters in both the Getty and the PFayum 4 papyrus fragments. Upsila, similarly formed in all, are decorated with serifs on the base of the vertical stroke at PFayum 4.11, Getty recto line 1, and Getty verso line 7.”

   “Inconsistent letter forms: e.g. upsila in 1.2; kappas in 1.7; long rho in πρωτον vs. short rho in ημετερα; epsila in επελθω.”
