Chapter 7, Drill a: Drill forming accusative and ablative in the third declension.

For each third declension noun or adjective, give accusative and ablative, either singular or plural as requested. Remember that you must know the stem from having learned the genitive, the second part of nouns now supplied in the vocabulary.

Example:
pater (singular) Answer: patrem patre: since the genitive given in the vocabulary is patris, the stem (what's left after taking off the -is, the genitive ending) is patr-, the stem, to which you add the accusative ending -em and ablative -e.
