For the formal study of the parthood relation, see [[mereology]]. Part can also mean: * In '''[[part (music)]]''': ** A part is the music played by an individual instrument or voice (or group of identical instruments or voices) within a larger work ** A part in great Highland Bagpipe music is a musical sentence * In the '''performing arts''', a part is an actor's role (see [[Role (performing arts)]]). * In '''mathematics''', a [[part (mathematics)]] is any geometric object such as a point, line, arc, circle, polygon, polyhedron, or polytope that can be joined together to form a whole. * In '''engineering''', a part is a component used in a higher-level mechanical or electrical assembly. Examples of parts are [[screw]]s, [[transistor]]s and other [[electronic component]]s, a specially shaped piece of metal required by the mechanism of a specific model of [[video cassette recorder]], and a myriad other examples. Parts required to replace broken parts in existing equipment are called [[spare part]]s or just spares. * In '''fashion''', the part or parting of a person's hair is the "watershed" line at which the hair is divided (often with a comb), and forms part of their [[hairstyle]]. Some people part their hair in the middle (a "center part," following the natural part of the hair), and some part their hair at one side or the other. * In '''preparing mixtures''', it is customary to specify an undefined amount of a mixture in either parts or [[percentage]]s. For example the [[cocktail]] known as a [[Martini (cocktail)|Martini]] is described as being made with 5 parts of [[gin]] to 1 of [[vermouth]]. This terminology can also be used in relation to cement and recipes. * In the [[Hebrew calendar]], a part (chelek) is 1/18 of a minute, or 3 1/3 seconds. {{Wiktionary}} {{disambig-cleanup}} [[cs:Díl]] [[de:Teil]] [[io:Parto]] [[ja:パート]] [[sk:Diel]]
