text: Allen and Greenough say that a vowel before [ŋn] is always long,  but W. Sidney Allen says that is based on an interpolation in Priscian, and the vowel was actually long or short depending on the root, as for example rēgnum [ˈreːŋ.nũː] from the root of rēx [reːks] , but magnus [ˈmaŋ.nʊs] from the root of magis [ˈma.ɡɪs] .
