Certainly. Allen and Greenough sec. 500:
The gerundive is sometimes used, like the present and perfect participles, in simple agreement with a noun:—
fortem et cōnservandum virum (Mil. 104), a brave man, and worthy to be preserved.
gravis iniūria facta est et nōn ferenda (Flacc. 84), a grave and intolerable wrong has been done.
Before we understand the gerundive of a deponent verb, we need to first understand the particples of deponent verbs.
Participles of Deponent Verbs
Deponent verbs are often described as verbs with "passive forms but active meanings." While this generally holds true, it ignores a crucial extra step: deponents have participles in both voices! (See Allen & ...
Weiss writes that
"The u-forms are characteristic of legal and archaizing style, e.g. pecuniae repetundae (the recovery of extorted money), and are found in the isolated forms secundus 'following' and rotundus 'round' (p. 444; emphasis mine - Alex B.).
Powell 2007/2011 adds that even though "the gerundive suffix in -undus, rather than -endus, has an old-...
Normally, when you passive a verb in Latin, the following happens:
Subject becomes a(b(s)) + ablative.
Direct object becomes subject.
All other constituents remain unchanged.
Note that a direct object is only that object which is directly governed by a verb (so without prepositions) and which is in the accusative.
Ciceroni parcitur ...
Nocendo is a gerund (noun) here, not a gerundive (adjective). Therefore, it's active in meaning. It's ablative to show the means by which Juno does good. Quae is f. nom. sing. and refers to Iunonem, who is the 'I' of the relative clause.
...I who alone do good by doing harm
(Note that sola couldn't be the object of nocendo (or the agent, because nocendo, ...
Yes, there is. A couple of notes:
Faciendus (-a, -um) is attested. Perseus gives 21 results of the former. These include several forms of faciendus + [esse] (est, erat, esset)
There is also a number of instances of gerund faciendum, -i, -o
Ad satis faciendum (Cic. Clu. 4):
Etenim tibi si in praesentia non potuero, tamen multae mihi ad ...
The gerund is only used in the singular, so for that reason alone praestandis has to be a gerundive.
The gerund is a verbal noun (and as a subject or object is replaced by the infinitive).
The gerundive is a verbal adjective; it adapts its form to the gender, number, and case of whatever it modifies.
There is no good analogue for this distinction in English,...
In my experience many languages confuse lack of desire and desire of the contrary.
For example, I would like to be able to say "I don't want coffee" as the negation of "I want coffee", meaning that I don't have a desire to have coffee.
To say that I am actively against drinking coffee, I would prefer to say "I want not to have coffee".
But, unfortunately, ...
In his Corso elementare di lingua latina ("Elementary Latin course", 1844), Vincenzo De Angelis deals with this in Volume 1, p. 191:
Se il verbo indica azione vi sarà il passivo, come amo ed amor... e perciò amans ed amatus-amaturus ed amandus. Ma ove indicasse uno stato intransitivo, nè il verbo vi sarà con questo doppio valore, e forma; nè participi ...
The following examples are of the negated gerundive clearly equivalent to a prohibition.
The pair faciendum / non faciendum is used to indicate positive and negative obligation, as evidenced by the parallelism with sequi / fugere.
Videsne ut quibus summa est in voluptate perspicuum sit quid iis faciendum sit aut non faciendum? ut nemo dubitet eorum ...
There are three or four impersonal verbs to express what is appropriate, or legal, or obligatory.
1 děcet, it is appropriate
2 dēděcet, it is inapproptiate, unseemly.
Ut nobis decet; As seems right to us.
Oratorem irasci minime decet, simulare non dēděcet. It is not professional for an orator to get angry, it is not unprofessional to pretend (to get ...
To clarify a little more.
In Gramatica Latina (latin grammar) by Santiago Segura:
Participe of passive future:
It is also called verbal adjective in -NDUS and gerundive and is formed by adding to the present theme the suffix -ND-US, -ND-A, -ND-UM, sometimes by -e- (3rd and 4th conjugation): ama- ndus, -a, -um; dele-nd-us, -a, -um; leg-e-nd-us, -a, -um; cap-...
Just like your Quod erat demonstrandum example suggests, you definitely need a gerundive form here :
quod erat faciendum
Depending on the context, you might want to consider facienda (n. pl, "that which is to be made").
The gerundive should be neuter if you just want to say "I need to read".
Any other form than singular neuter should only be used when the gerundive modifies a noun.
The modified noun can in principle be left implicit; consider:
Ubi est ista scriptio? Mihi legenda est!
Where is that writing? I have to read it!
The fact that the gerundive is not neuter ...
I don't think so. First, are you sure that pergit can be used in this sense? I would use pergo to indicate a sense of progression, and I would have an agent in mind as its subject, someone who continues to move in a certain direction. Perhaps permanet or perstat would fit?
As to the gerundive construction, i.e. a gerundive that is used dominantly, I believe ...
Allen and Greenough (504) say that a gerund in the genitive can take an accusative object, "especially a neuter pronoun or a neuter adjective used substantivally". Examples:
nulla causa iusta cuiquam esse potest contra patriam arma capiendi (Cic. Phil. 2 53)
artem vera ac falsa diiudicandi (Cic. Or. 2.157)
They say that such constructions are rare ...
A basic problem here is that trust or belief works with dative in Latin.
I trust you.
One can express obligation with gerunds, putting the subject (implicit ego) into dative:
Mihi tibi credendum est.
I have to trust you.
But given the flexible word order, which one of mihi and tibi is supposed to be the subject and which ...
It is indeed possible: in such cases, one uses a/ab/abs with the person who is to act, to avoid ambiguity.
Weimer (above) provides a reference, Gildersleeve & Lodge 355:
To avoid ambiguity, especially when the verb itself takes the Dat., the Abl. with ab (a) is employed for the sake of clearness...When there is no ambiguity, there is no need of ab. [...
Just to add on to Alex B's answer, though I can't offer as authoritative of sources:
Would it be appropriate to occasionally make the replacement in any context?
In the late Republican period, the answer seems to be yes, but it sounds a bit archaic. I'd compare it to putting the object before the verb in English ("speaking with the object the verb ...
I think that the meanings attributed by sumelic to nasciturus and nascendus ("about to be born" and "needing to be born", respectively) are more or less appropriate (NB: the modal meaning "needing" is not present in all gerundives. Rather the "conditio sine qua non" for gerundives seems to be that their argument must be a Patient/Theme). The form nasciturus ...
