[1294.] With verbs of separating and abstaining, the ablative is regularly used ([1302]). But the genitive is sometimes found in poetry: as, mē omnium labōrum levās, Pl. R. 247, thou riddest me of all my woes. abstinētō īrārum calidaeque rixae, H. 3, 27, 69, from bursts of rage keep thou and hot affray.
[IV. THE GENITIVE OF EXCLAMATION.]
[1295.] In poetry, the genitive with an adjective in agreement occurs two or three times in exclamation: as, foederis heu tacitī, Prop. 5, 7, 21, alas, that secret covenant. Usually the nominative ([1117]), or the accusative ([1149]).
[THE ABLATIVE.]
[1296.] The ablative is used principally with verbs and their participles, or with adjectives, and consists of three cases that were originally distinct.
[1297.] I. The Ablative proper denotes that from which something parts or proceeds ([1302]).
The ablative proper is often accompanied by the prepositions ab, dē, ex, prae, prō, sine, or tenus.
[1298.] With the ablative proper two other cases, originally distinct, a locative case and an instrumental case, were confounded, and merged under the common name of the ablative.
[1299.] II. The Locative case denotes the place in, at, or on which action occurs. A few forms of the locative proper are still preserved ([1331]). But the place where is ordinarily denoted by the locative ablative ([1342]).
