Tacy

Tacy is a feminine given name found in English-speaking regions. It is most often used as a standalone name but can also function as a diminutive or nickname for other names such as Stacy, Stasia, or Tatiana, depending on personal or family preference. The frequency of the name is relatively low compared with more common variants, and it is most frequently encountered in contemporary name records in the United States and other English-speaking countries.

Because of its multiple possible origins, the precise etymology of Tacy is not fixed. It is commonly treated as a variant or shortened form of Stacy or Stasia, which themselves derive from Latin forms associated with the name Anastasia or from other religious or cultural sources in different historical periods. The spelling Tacy can reflect phonetic preference or family tradition rather than a single standardized lineage.

People named Tacy may be addressed by the nickname Tacy or its longer forms in daily life; as a given name, it offers a concise, informal option in the broader tradition of early- to mid-20th-century English names. There are no widely recognized figures whose primary public identity is solely under the name Tacy, and the name does not have a formal scholarly or organizational meaning beyond its role as a personal name in most contexts.

Related names include Stacy, Stasia, Tasia, Tasie, and other variants of similar phonology. In discussions of onomastics, Tacy is cited as an example of short forms that migrate across cultures and time.
