What does retroflex mean?
Retroflex means bent or directed backward. The word is also an important term in linguistics, where it describes a sound made with the tip of the tongue curled back toward the roof of the mouth, or sometimes with the tongue body retracted. Such sounds occur in several languages and can distinguish one language or regional variety from another. In discussions of English pronunciation, “retroflex r” may refer to an r-like sound produced with a curled tongue, although the precise description depends on the accent and the phonetic framework being used. Outside linguistics, retroflex is chiefly a descriptive term for anything that bends backward. Its specialized meaning makes it useful when discussing articulation, dialect variation, and the sounds that help identify a speaker's linguistic background.

Where does retroflex come from?
Retroflex comes from Latin retro, meaning “backward,” and flexus, the past participle of flectere, meaning “to bend.” The English word was formed in the 19th century and was initially used chiefly for a backward-bent form or movement. Its linguistic sense developed from the anatomical position of a retracted or curled tongue.
