Correct spelling for the English word "INCUBINE" is [ˈɪnkjuːbˌa͡ɪn], [ˈɪnkjuːbˌaɪn], [ˈɪ_n_k_j_uː_b_ˌaɪ_n] (IPA phonetic alphabet).
An incubine is a term historically used to describe a woman who is kept as a mistress by a man, typically a wealthy or powerful individual. The word is derived from the Latin word "incubo," meaning to lie upon or sleep with, and it has been in use for centuries to refer to a woman who engages in a sexual relationship with a man outside of marriage.
In its historical context, an incubine was often maintained in a relationship not recognized by society or formalized through marriage, often due to legal or social restrictions that prevented the man from divorcing his current spouse or marrying the woman he was involved with. The status of an incubine usually granted her financial support and a place to live, but she was not accorded the same rights and privileges as a wife.
The term has been largely supplanted in contemporary usage by other terms such as mistress or paramour. However, it continues to carry connotations of a woman who is in a subservient or marginalized position within a relationship, often lacking the legal or social rights and recognition granted to a wife. The use of the term today may also connote a relationship that is secretive in nature, suggesting a lack of public acknowledgment or legitimacy.
