I-Stems with Ablative -i

Here’s the other half of that list that I started in (this post). These are the class of consonantal adjectives that tend not to operate as quasi-nouns, and therefore tend to take -i in the ablative, rather than -e.

  • āmēns, āmentis, frantic, crazed
  • anceps, ancipis, double, doubtful
  • concors, concordis, agreed, joint
  • dēgener, dēgeneris, low-born, weak
  • hebes, hebetis, dull, blunt
  • ingēns, ingentis, huge, vast
  • inops, inopis, needy, helpless
  • memor, memoris, mindful of
  • pār, paris, alike, equal to
  • perpes, perpetis, lasting
  • praeceps, praecipitis, headlong
  • praepes, praepitis, nimble, winged
  • teres, teretis, smooth

Sorry for the relative obscurity of these last two posts. The thing is, they cover a few footnotes in Allen and Greenough that I feel should be out there on the Internet, preferably with a basic entry format and definition.
