kinesthesia[kin′is t̸hē′z̸hə, -z̸hē ə]
Origin of kinesthesiaModern Latin ; from Classical Greek kinein, to move (see cite) + aisthēsis, perception: for Indo-European base see aesthetic
Origin of kinesthesiaGreek kīnein, to move; see kei&schwa;- in Indo-European roots + esthesia.
(countable and uncountable, plural kinesthesias) (abstract)
- Sensation or perception of motion.
- (see usage note) proprioception or static position sense; the perception of the position and posture of the body; also, more broadly, including the motion of the body as well.
Pronunciation The traditional rules of pronunciation of Greco-Latin vocabulary prefer the I in the first syllable to be long. The more common pronunciation with short I is by analogy with other words from this root such as kinetic and kinesiology where short I is expected.

Meaning The etymological meaning of the word as used in physiology refers specifically to the motion of the body, and a distinction between kinesthesia and the sense of the position of the body is sometimes made in technical texts. In popular use the distinction is made less often.

Ancient Greek κινέω (cineō, put in motion) + αἴσθησις (aesthēsis, sensation) in form -αισθησία after anaesthesia, etc. Compare kinesthesis and Modern Greek κιναισθησία.
If this word were borrowed on fully traditional principles it would be cinesthesia (cinaesthesia); compare cinema from the same root. But more often this Greek root is spelled and pronounced with a k, and in the case of kinesthesia this avoids inconvenient homophony with synaesthesia, the sensation of one type of perception as another (e.g. the perception of smells as colors). Nevertheless the words are still occasionally confused; e.g. .
