 110 (number)

110 (one hundred [and] ten) is the natural number following 109 and preceding 111.
It is also known as "eleventy", a term made famous by linguist and author J. R. R. Tolkien (Bilbo Baggins celebrates his eleventyfirst birthday at the beginning of The Lord of the Rings) and derived from the Old English hund endleofantig.^{[1]} When the word eleventy is used, it may indicate the exact number (110), or more commonly an indefinite large number such as gazillion.
