Like A&G, I would like to conclude my series on i-stems with a short assessment of the basic rules and variations associated with the i-stem class.
A&G paint a picture of cultural amnesia regarding Roman relations with the i-stem. As I have shown in previous posts, in all but the genitive plural (ium), and the neuter accusative/nominative plural (ia), the unique i-stem endings are rare or optional. (cf. the status of English ‘who/m’).
- The nominative singular could be -is (sitis, is) but also ēs/-s/–x, etc.
- The accusative singular could be -im but also -em.
- The ablative singular could be -ī or it could be -e.
- The accusative masc/fem plural might be -īs but it’s usually -ēs.
