Questions & Answers about Sei diventata madre e la maternità è impegnativa; ogni tanto un castigo è comprensibile.
Since this lesson is about connectors of justification, how could we add d'altronde or del resto to this sentence?
While they aren't used in this specific sentence, you could easily insert either to emphasize your reasoning. For example: la maternità è impegnativa; d'altronde, ogni tanto un castigo è comprensibile (motherhood is demanding; after all, sometimes a punishment is understandable). Both connectors perfectly link the difficulty of the situation to the justification of the action.
Why does diventare use the feminine ending in diventata?
Because diventare (to become) is an intransitive verb indicating a change of state, so it requires the auxiliary verb essere in compound tenses. Whenever a verb uses essere, its past participle must agree in gender and number with the subject. Here, the subject is clearly female because she has become a mother (madre).
