Isaac is an ancient name of Hebrew origin, meaning 'he will laugh'. It is derived from the Hebrew name Yitzchak, which was borne by the patriarch Isaac in the Bible. He was the son of Abraham and Sarah, and his birth was foretold after years of prayer, hence the laughter associated with his name. Throughout history, Isaac has been a popular name among Jewish communities, and over time, it has also gained acceptance among Christians and Muslims due to its biblical significance. It is composed of three consonants - Yod, Shin, and Kaf - which form the root verb 'to laugh' in Hebrew.
The name Isaac experienced fluctuations in popularity over the years with peaks in the late 80s and late 90s, and a resurgence around the mid-2000s to early 2010s.
