1It is unknown whether Classical Latin preserved (or would have preserved) the shortness of the original Greek short ending.
2It is unknown whether adjectives of this type would use i-stem or consonant-stem endings in Classical Latin: the relevant forms are not attested. Depending on the word, either ending or both may be attested in New Latin.
