What is the origin of word yard?

The word "yard" has a complex etymology. It originally comes from the Old English word "gierd", which meant a rod or a stick. This word was also used to refer to a measure of length, equivalent to three feet. Over time, the word "gierd" evolved into "yard" and began to be used in a variety of contexts. Its meaning expanded to include the area of land around a house or building, a unit of measurement equal to three feet, and eventually, a place for sports and other activities. In the United States, the term "yard" is commonly used to refer to the outdoor area surrounding a house, while in British English it is more commonly used to refer to a unit of measurement or a sports field.
