Salvete.
I’ve come across the following and whilst I think the meaning is ‘aren’t you ashamed to deny the poor tutor the wages’ I am nevertheless, puzzled by the grammar.
Nonne te pudet pauperi magistro mercedem negare?
So, what I think is going on is that the impersonal verb ‘pudet’ is completed by the infinitive ‘negare’. Negare can be transitive or intransitive but appears to my untutored eye to be both here. The dative ‘pauperi magistro’ is the subject of the infinitive, is it not? Is the accusative ‘mercedem’ simultaneously the subject of the infinitive?
I’m teaching myself and my method is to glean every bit of understanding I can as I go along. If I ignored my uncertainty and simply ploughed on I’d be cheating myself. So I’m hoping someone can assist by suggesting how the sentence works.
