Definition of placeholder

placeholdernoun

chỗ giữ chỗ

/ˈpleɪshəʊldə(r)//ˈpleɪshəʊldər/

The word "placeholder" has its roots in Latin. In Latin, the word "locum tenens" (pronounced low-koom ten-ens) means "holding its place" or "filling a space." This phrase was used to describe a person who temporarily filled a position or a document that served as a temporary substitute for a future, and more complete, document. Over time, the phrase "locum tenens" evolved into the English word "placeholder," which initially referred to a person or thing that filled a position or space temporarily. The meaning of the word expanded to include any item or piece of writing that held a position or spot until a more permanent solution was found. Today, the term "placeholder" is commonly used in various contexts, including technology, design, and everyday language, to describe a temporary or provisional solution that holds a specific spot until a more permanent one is found.
