About the name Isac
Isaac comes from the Hebrew Yiṣḥāq, which Wiktionary glosses as 'he laughs, he will laugh', in reference to Sarah's laughter in the Book of Genesis; Behind the Name gives 'he will laugh, he will rejoice', from the verb tsaḥaq, 'to laugh'. The Dicionário de Nomes em Uso no Brasil (Dictionary of Names in Use in Brazil), citing José Pedro Machado, traces the name to the Biblical Latin Isaac, from the Vulgate, gives Isac as a Latin variant, and records Isaque as a Portuguese spelling already in use in the fourteenth century; Isaac, Isak and Isack appear among the Portuguese variants, and Issac among the Galician ones. In the 2022 Census, IBGE recorded 64,850 people named Isac, with a median age of 11. The spellings in the group differ in the ending (-c, -ac, -k, -ck) and in single or double S.
