What does retroflexion mean?
Retroflexion most commonly describes a manner of speech in which the tip of the tongue is raised or curled backward. It is particularly associated with the “r” sound, though retroflex versions of “s” and other consonants also occur in languages such as Hindi, Tamil, and some Mandarin varieties. Speakers of English may encounter the term in linguistics courses, pronunciation guides, or descriptions of regional accents. Retroflexion also has a medical sense: backward bending of a body part, most notably the uterus. In this context, it describes a physical position or curvature rather than a vocal articulation. The word is precise and technical, with “retro-” indicating a backward direction and “flexion” referring to bending or turning. Although relatively uncommon in everyday speech, it is useful whenever one needs to distinguish a backward-curled tongue movement from an ordinary forward or central articulation.
nounRetroflexion is the articulation of a speech sound by curling or raising the tip of the tongue backward, especially in sounds such as /r/ or /s/. In medicine, it refers to the backward bending of a body part, especially the uterus.

Where does retroflexion come from?
Retroflexion was formed in English from retro- and flexion, combining the ideas of backward direction and bending. Flexion ultimately comes through Latin flexionem, a derivative of flectere, “to bend,” the same Latin root found in flex, reflex, and circumflex. The linguistic sense developed alongside the adjective retroflex, while the medical sense refers to a part bending backward.
