[i] 1st / 2nd declension adjectives, like some 2nd declension
masculine nouns, can end in -er. These will also decline in exactly the
same way and, as with this noun type:
(1) some lose the /e/ of the nominative singular when endings
are added
- aeger, aegra, aegrum: sick [aeger, -gra, -grum]
- impiger, -gra, -grum: energetic; diligent
- pulcher, pulchra, pulchrum: beautiful [pulcher, -chra, -chrum]
(2) some adjectives retain the /e/
- miser, misera, miserum: wretched [miser, -a, -um]
