Nassim is an Arabic name meaning 'gentle breeze', traditionally used as both a given name and surname throughout the Arab world. It has been popularized by notable figures such as Nassim al-Ghassani, a Moroccan scholar and poet from the 14th century, and Nassim Taleb, a Lebanese-American philosopher and mathematician. The name is often associated with qualities like gentleness, grace, and tranquility, reflecting the calm nature of a breeze. However, personal traits are not solely determined by one's name.
