Courtship is the period when some couples become familiar with each other prior to a possible marriage or committed relationship. Courtship traditionally may begin after a betrothal and may conclude with the celebration of marriage. A courtship may be an informal and private matter between two people or may be a public affair, or a formal arrangement with family approval. Traditionally, in the case of a formal heterosexual engagement, it is the role of a male to actively "court" or "woo" a female, thus encouraging the female to be receptive to a marriage proposal.
