نبيل "Nabil" is a boy name. إنها means "she/it is". عائشة "Aisha" is a girl name.

إنَّ has two major uses in this language. First, it is often used at the start of a sentence and has the meaning of “verily” or “indeed.” Often today we do not even translate the word. Often these sentences are equational sentences, Like your sentences: إنها عائشة = Verily/ indeed she is Aysha, “Verily” is in parenthesis because it is not really necessary to translate. Sometimes it has the meaning of “indeed” but usually it too can be left out.

"It is" or "she is"
