- “valētūdō modo bona sit ” (Brut. 64) , provided the health be good.

- “ tantum nē noceat ” (Ov. M. 9.21) , only let it do no harm.
[*] Note.--The Subjunctive with modo is hortatory or optative; that with dum and dummodo, a development from the use of the Subjunctive with dum in temporal clauses, § 553 (compare the colloquial so long as my health is good, I don't care).[*] a. The Hortatory Subjunctive without a particle sometimes expresses a proviso:—
- “ sint Maecēnātēs, nōn deerunt Marōnēs ” (Mart. 8.56.5 ) , so there be Mœcenases, Virgils will not be lacking.
- “probāta condiciō est, sed ita ut ille praesidia dēdūceret ” (Att. 7.14.1) , the terms were approved, but only on condition that he should withdraw the garrisons.
[*] Note.--This is a development of the construction of Characteristic or Result.For a clause of Characteristic expressing Proviso, see § 535. d.
