UNUS NAUTA (ONE SAILOR) ADEJECTIVES

Ūter: Which (of two)?
Nullus: None, no
Ullus: Any, some
Sōlus: Only, alone
Neuter: Neither (of two)
Alter: One (of two), other (of two)
Ūterque: Each (of two), both*
Tōtus: Whole, all (of), entire
Alius: One (s.), some (pl.); other (s.), others (pl.)

All the above adjectives are quite common in Latin and are partially irregular. Most of the forms are like 1st and 2nd declension adjectives such as magnus and bonus. However, the genitive singular ending for all 3 genders is –ius and the dative singular for all 3 genders is ī. These gen. and dat. s. endings are like pronouns such as qui, quae, quod and ille, illa, illud (in fact, the adjective alius also has a similar neuter singular nominative and accusative with a –d instead of an m, “aliud”).

NOTES:
The neuter singular accusative utrum can introduce a two-part question with an for the second part.
Utrum veniunt an non?
Are they coming or not? -Notice that we do not translate the utrum in English.
Alter and alius are translated in special ways when they occur twice or more.
