| 6241627823 | gerund | The gerund is a *verbal noun*, always *active* in force, which only appears in the genitive, dative, accusative, and ablative singular. It is formed by adding *-nd-* to the present stem of the verb (-iend- for i-stem and 4th conj.) plus the neuter singular endings of the second declension. The gerund expresses purpose when used with "ad" (+ ACC) or "causa" (+ GEN). e.g. "ad legendum" = "for the purpose of reading" | 0 | |
| 6241627824 | gerundive | The gerundive is a *verbal adjective*, always *passive* in force, which appears in all cases and both numbers. It is formed by adding *-ndus, -a, -um* (-iendus, -a, um for i-stem and 4th conj.) to the stem of a verb, and carries the notion of *necessity, obligation, or propriety*. Like the gerund, the gerundive can be used with "ad" + ACC or GEN + "causa" to express purpose. | 1 | |
| 6241627825 | passive periphrastic | The Future Passive Periphrastic is comprised of the *gerundive* and a form of *"sum,"* with the gerundive agreeing with the subject of the sentence in number, case and gender. The construction is passive and always conveys a notion of *obligation, necessity, or propriety*. The agent of the action (if expressed) is in the *dative* case. ex: "Carthago delenda est" = "Carthage must be destroyed" | 2 | |
| 6241627826 | supine | The supine is a *verbal noun of the fourth declension* and appears only in the accusative and ablative singulars. The supine in *-um* may be used after verbs of motion *to express purpose*, or with the passive infinitive "iri" (from "eo") *to form the rare future passive infinitive*. The supine in -u is used with a few adjectives and nouns *to express an ablative of respect or specification*. | 3 | |
| 6241627827 | indirect statement | Indirect statement ("oratio obliqua") is introduced by verbs of thinking, perceiving, knowing, saying, etc. and takes *an accusative subject + an infinitive*. If the subject of indirect statement is identical to the subject of the main verb, the accusative reflexive pronoun is used as the subject. Indirect statements follow ordinary sequence of tenses - a *present* infinitive expresses the *same time* as the main verb, a *perfect* infinitive expresses *time before*, a *future* infinitive expresses *time after*. | 4 | |
| 6241627828 | indirect question | An indirect question is in a dependent clause *introduced by a "question" word*. The verb in an indirect question is always *subjunctive*, but the main verb of the sentence may be either indicative or subjunctive. Indirect questions follow sequence of tenses. | 5 | |
| 6241627829 | indirect command | An indirect command is an "ut" (or "ne") clause that expresses a *command, wish, hope,* etc. The verb in an indirect command is always *subjunctive*, though it is often translated like an infinitive. | 6 | |
| 6241627830 | ut clause | An ut-clause is a subordinate clause introduced by the conjunction *"ut"* with the verb of the subordinate clause in the *subjunctive* mood. The negative of "ut" is "ne". | 7 | |
| 6241627831 | fearing clause | Fearing clauses are ut-clauses signaled by a main verb of "fearing". Note that if the speaker fears something *will* happen, *"ne"* is used; if the speaker fears something *will not* happen, *"ut"* is used. | 8 | |
| 6241627832 | result clause | Result clauses are ut-clauses that *express the result of an action* ("ut" is translated "that"). They are often signaled by words that carry some adverbial meaning of "so," such as tam, ita, sic, adeo, tot, tantus -a - um, etc. | 9 | |
| 6241627833 | purpose clause | Purpose clauses are ut-clauses that *express the purpose of an action* ("ut" is translated "in order to" or "for the purpose of"). Note that "quo" is used instead of "ut" if the purpose clause contains a comparative adjective or adverb. | 10 | |
| 6241627834 | jussive/hortatory subjunctive | The subjunctive is often used to *express a command or exhortation*. This construction is called *"jussive"* when occurring in the *third person*, and *"hortatory"* when occurring in the *first person*. | 11 | |
| 6241627835 | potential subjunctive | The subjunctive can be used as a main verb to *express a possibility*. This is called the potential subjunctive and is translated "would (verb)" or "may (verb)". | 12 | |
| 6241627836 | deliberative subjunctive | The subjunctive can be used, generally with the first person singular, when a speaker is *deliberating* or *expressing doubt/disbelief*. The deliberative subjunctive often takes the form of a rhetorical question. | 13 | |
| 6241627837 | optative subjunctive | The optative subjunctive is used in wishes and usually translates with the English words "if only". The *present* subjunctive accompanied by "utinam" or "ut" expresses a future wish *capable of fulfillment*. Contrary-to-fact wishes use the *imperfect* subjunctive for *present* time and the *pluperfect* subjunctive for *past* time. | 14 | |
| 6241627838 | simple conditionals | If the author is making a *plain statement of fact*, conditionals appear with the *indicative*. These can take three forms: "simple present," "simple past," and "future more vivid". | 15 | |
| 6241627839 | future less vivid conditional | Future less vivid conditionals express a *possible* condition for the future, either with *two present subjunctives* or *a present and a perfect subjunctive*. The two verbs are often translated "should" and "would," respectively. | 16 | |
| 6241627840 | contrary to fact conditionals | Contrary to fact conditionals express something that either could not happen or did not happen. *Present* contrafactual statements use *two imperfect subjunctives* (translated "were to...would"), and *past* contrafactual statements use *two pluperfect subjunctives* (translated "had...would have") | 17 | |
| 6241627841 | conditionals in indirect statement | If a "si" clause is in indirect speech, the verbs are subjunctive but do not carry any contrafactual implications. | 18 | |
