The word "titter" originated in the 16th century and its etymology can be traced back to Middle English. It is believed to have derived from the Old English word "titeren", which meant to shake or tremble. This, in turn, derived from the Old Norse word "titra", meaning to quiver. Over time, the meaning of "titter" evolved to refer to a restrained laughter or giggling sound, which is the modern usage of the word.
