Isaac
Isaac comes from the Hebrew "Yitzhak," meaning "he laughs" — from "tzachak" (to laugh). In the Hebrew Bible, Isaac was the son of Abraham and Sarah, born when Abraham was 100 and Sarah was 90. Sarah laughed when she heard she would have a child — and the name carries that laughter. Isaac was the father of Jacob and Esau. Isaac was a top-100 American name from 1880 to 1920, declined mid-century, and then had a remarkable revival. It entered the top 50 in 2009 and continues to climb. Isaac Newton (1642-1727), the physicist whose "Principia Mathematica" (1687) founded classical mechanics, is the most famous scientific bearer. Isaac Asimov (1920-1992), the science fiction author of "I, Robot" (1950) and the "Foundation" series, gave the name literary weight. I find Isaac has an elegant, slightly biblical quality — the "I" opening is open, and the "aac" ending gives it a distinctive sound. The "z" (in pronunciation) gives it a slight edge. Isaac is one of the most successful Old Testament revivals. Isaac is a male name of Hebrew origin that means "He laughs". Biblical, scientific, and quietly humorous. The name sounds serious. Isaacs tend to be thoughtful. US top 50 since 2009. Rising. Well-known people named Isaac include Isaac (biblical), Isaac Newton (physicist), Isaac Asimov (author), Isaac (Hebrew name). Common variations and related forms of Isaac include Yitzhak (Hebrew), Isaak (German), Isacco (Italian), Izaak (Polish).
