Just a little bit is an expression used to describe a small amount of something. It can be expressed in several ways, such as IOTA (4 letters), SMIDGEN (7 letters), and SKOSH (5 letters). IOTA is derived from the Greek letter meaning 'very small amount'. SMIDGEN is a colloquial term that originated in the United States in the 19th century, and is used to describe a tiny amount. SKOSH is a Japanese word that means 'a little bit'. All three terms are used to express the same idea: a very small amount of something.
