Definition & Meaning of "tranny"in English

What is the origin of the term "tranny" and how is it used?

Tranny is a slang term that appeared in late 20th-century English as a shorthand for "transgender," particularly referring to trans women. The word originated as an informal abbreviation but quickly gained a derogatory and offensive connotation, often used to mock, objectify, or belittle transgender people. Today, it is widely recognized as highly offensive and is considered a slur; it is avoided in respectful conversation and only appears in historical or critical discussions of transphobic language.
