Well, I suppose you could. Most of the meaning would be lost, but I presume it would roughly be the equivalent of saying in English “We should give away [part or all of our possessions, ie what we have available to give away].” Should it be included on a more complex context, then it would be even clearer. “Esuriens ab nobis panem rogat. Habemus panem. Ei dare debemus.”
Is ‘EI’ which I assume is the plural for IS considered to
be the direct obj or the indirect obj? I would say that it
is not since it is in the nominative.
If it were the direct object it would have been ‘EIS’ or ‘EOS’
It looks like the nominative in the sentence ‘EI DARE DEBEMUS’.
Oh, but yes. My mistake. When you wrote “It says that the objective infinitive Dare may or may not have a direct or indirect object”, I didn’t read the last part!
I would ask for someone more knowledgeable to state their opinion, but I would believe that, yes, “Dare debemus” would work nicely, without neither direct nor indirect object.
