If the action of the independent clause happens only under the particular circumstances described by the dependent clause, the dependent clause is referred to a clause of proviso. There are a number of words that can introduce clauses of proviso (dum, dummodo, modo), which usually are translated as “if only”, “only”, or “provided that.” The clause of proviso always features a subjunctive verb in either the present or imperfect subjunctive. Clauses of proviso are negated by ne.
Below are some examples of proviso clauses (subjunctive verbs in the proviso clauses are bolded):
Dum metuant, oderint. (So long as they are scared, let them be hateful)
Magnō timore mē liberabis, dummodo inter me atque te murus intersit. (You will free me from great fear, so long as there is a wall between me and you).
Erimus felices, modo ne discedas. (We will be happy, provided that you do not leave.)
Identify the type(s) of subordinate clause in the following sentences and, then, translate.
