Benjamin is a popular given name for males, derived from Hebrew בִּנְיָמִין, Binyāmīn, translating as "Son of my right [hand]", though in the Samaritan Pentateuch, the name appears as ࠁࠍࠉࠌࠉࠌ, "Binyaamem" 'Son of my days'. It is often shortened to Ben, and sometimes to Benny, or Benjy. Benjamin is also a patronymic surname. Like many biblical names, it is popular in the Jewish, Christian and Muslim faiths alike, having many variant forms in other languages.
The "Benjamin of the family" is a phrase used in several languages to refer to the youngest son - especially when he is much younger than his brothers; sometimes the name is chosen for a son born to mature parents unlikely to have more children, especially if he has several older siblings. Both of these usages derive from the biblical son of Jacob of that name, who occupied that position in his family.
