Ypos
From Simon Online
Ypos grece equus sed melius per .i. iota.
Apparatus:
melius om. e
Translation:
Ypos is Greek for Latin equus {"horse"}, but it is better written with the Greek letter iota, "i" {i.e. ipos}.
Commentary:
Cf. Greek ἵππος /híppos/ "horse; mare". Simon is aware of the unetymological spelling with "y", but "Y,y" and "I,i" had become virtually interchangeable in late and medieval Latin.
Psilosis, i.e. the dropping of /h/, and the reduction of double consonants like /pp/ to a single consonant /p/ occurred in Greek as early as the Koine period (300 BC – 300 AD).
Simon's pronunciation and that of his contemporary Greek speakers would have been /ípos/.
