ABLATIVE

• Shows where a place is, or from where motion is directed. No prepositions are needed to show movement from cities, towns, or small islands. Eg. Roma from Rome.
• Shows the cause of an action without using a preposition.
• Use "a"/"ab" and the ablative case for agents in the passive voice. Instruments in the passive voice take the ablative case, but without a preposition.
• Used to show when something happens. Eg. anno in/during a year; hora in/during an hour; sex annis in/during six years.
• Used for comparisons; the second of two things being compared takes the ablative. Eg. Tuus longior est suo Yours is longer than his
• Used to create a dependent clause using a noun and a participle ("ablative absolute" clause).
