Like all neuter nouns in Latin, neuter nouns of the third declension use the same form in the accusative as the nominative, and take the -a ending in the plural nominative and accusative. Otherwise, they are formed the same way as the masculine and feminine third declension nouns that we learned in the last lesson.

When we describe the manner in which something was done, we use the ablative with the preposition cum. If the noun is modified by an adjective, cum may be omitted, or placed between the adjective and the noun in this order: adjective cum noun.

• Aquam cum cura portavit. - He carried the water with care.
• Aquam magna cum cura portavit. - He carried the water with great care.
• Aquam magna cura portavit. - He carried the water with great care.

We've learned several different uses of the ablative, so it may help to review the others.

• Aquam carro portavit. - He carried the water with a cart. (Ablative of means, no preposition.)
• Aquam cum amico portavit. - He carried the water with a friend. (Ablative of accompaniment, takes cum.)
• Aquam in via portavit. - He carried the water on the road. (Ablative of place where, takes in.)
• Aquam ex villa portavit. - He carried the water out of the field. (Ablative of place from which, takes a preposition like ex, de, etc.)
