Kissing is also a means of expressing greetings between people of close acquaintance, often family members. This typically involves kissing on the cheek.
Kissing may also be used to signify reverence and subordination, as in kissing the ring of a king or pope.
When not an expression of romantic affection, a kiss is a largely symbolic gesture, in that the purpose of the kiss is to convey a meaning, such as salutations or subordination, rather than to experience the physical sensations associated with kissing. In romantic and sexual kissing, the physical sensations are often primary. Thus romantic kissing tends to be more intense and prolonged (see tongue kiss).
The term Kissing Hands is used to formally describe the appointment of the senior state figures to office by British monarchs. Though in the past, the monarch's hand was actually kissed, this is no longer so. When figures such as the British Prime Minister, cabinet members and diplomatics are formally appointed, they are said to have Kissed Hands.
