A '''gesture''' is a form of [[non-verbal communication]] or non-vocal [[communication]] in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, [[speech]]. Gestures include movement of the [[hand]]s, [[face]], or other parts of the [[Human body|body]]. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely [[Emotional expression|expressive]] displays, [[proxemics]], or displays of [[joint attention]].<ref name=Kendon>Kendon, Adam. (2004) ''Gesture: Visible Action as Utterance''.

Gesticulation and speech work independently of each other, but join to provide emphasis and meaning.
Gesture processing takes place in areas of the brain such as [[Broca's area|Broca's]] and [[Wernicke's area]]s, which are used by [[speech]] and [[sign language]].<ref name="Xu">{{cite journal | last1 = Xu | first1 = J | last2 = Gannon | first2 = PJ | last3 = Emmorey | first3 = K | last4 = Smith | first4 = JF | last5 = Braun | first5 = AR | year = 2009 | title = Symbolic gestures and spoken language are processed by a common neural system | journal = Proc Natl Acad Sci U S A | volume = 106 | issue = 49| pages = 20664–20669 | doi = 10.1073/pnas.0909197106 | pmid = 19923436 | pmc = 2779203 | bibcode = 2009PNAS..10620664X | doi-access = free }}</ref> In fact, language is thought by some scholars to have evolved in ''
