A '''partner''' is a person who is involved with one or more others in a common interest. In [[business]] partners may refer to members of [[profession]]al practice or those who run and finance a [[company]]. A ''silent partner'' or a ''sleeping partner'' refers to someone who has made an [[investment]] in the business and shares the [[profit]]s but takes no part in the day-to-day management.
Partner is sometimes used as a synonym for a [[husband]] or a [[wife]] but nowadays also includes couples who cohabit out of wedlock or in a [[same-sex marriage]].
In sports and games a partner is one of a pair who play together as a team; e.g. [[tennis]], [[bowls]], or [[bridge]].
When two people dance together, such as in ballroom dancing or ballet then they are as known as dance-partners
