Trachillos
From Simon Online
Trachilos grece collum.
Apparatus:
Trachillos AC e | Trachilos B f
Translation:
Trachillos is Greek for Latin collum {"neck"}.
Commentary:
Greek τράχηλος /trákhēlos/ means "neck, throat".
The word shows the effect of the itacist sound change η > ι {/ē/ > /i/}, resulting in /trákhilos/, the pronunciation Simon is portraying.
