Questions & Answers about Quies in bibliotheca discipulis grata est.

Why is quies the subject, even though it ends in -es and looks plural?

Quies is nominative singular, not plural.

This is a common point of confusion, because English speakers often expect a singular noun not to end in -es. But Latin nouns do not follow English-looking patterns. Quies is a third-declension noun, and its dictionary form is:

• quies, quietis (f.) = rest, quiet, peace

In this sentence, quies is the subject because:

• it is in the nominative
• the verb is est = is (singular)
• the adjective grata is also singular and agrees with it

So quies means quiet/rest as one singular idea.

Why is grata feminine?

Because grata agrees with quies, and quies is a feminine noun.

In Latin, adjectives agree with the noun they describe in:

• gender
• number
• case

So here:

• quies = nominative singular feminine
• grata = nominative singular feminine

That is why Latin uses grata, not gratus or gratum.
