2. Grūs is declined like sūs, except that the Dative and Ablative Plural
are always gruibus.

3. Juppiter is for Jou-pater, and therefore contains the same stem as in
Jov-is, Jov-Ä«, etc.

Nāvis was originally a diphthong stem ending in au-, but it has passed over
to the ĭ-stems (§ 37). Its ablative often ends in -ī.
