Knocked for a loop and thrown for a loop are American terms that appear in the early twentieth century. These phrases are idioms, or a word, group of words or phrase that has a figurative meaning that is not easily deduced from its literal meaning. We will examine the definition of knocked for a loop and thrown for a loop, where these terms came from and some examples of their use in sentences.

Knocked for a loop and thrown for a loop mean to be astonished, to be surprised, to be awestruck or to be confused. Knocked for a loop is the older of the two terms and dates back at least to the 1920s to the sport of boxing. At that time, knocked for a loop had a literal meaning of being punched so badly that the boxer falls backward, even rolling over in a somersault fashion due to the impact. The corresponding idiom thrown for a loop appeared about a decade later, and the two literal phrases took on a figurative meaning.
