Homosexualist

[Merna]

A term preferred by some writers in preference to using homosexual as a noun.
In a newsmagazine cover article on Gore [Vidal] in the late 1970s, the celebrated author and essayist explained that, since homosexual is used as an adjective (homosexual fantasy), the noun form needed something more, well, distinctive and substantive: he used homosexualist to describe someone who is gay in practice, or as a state of being.
One doesnt argue lightly with Gore Vidal but there are precedents either way in forming nouns. Alcoholic drink / Joes an alcoholic, uses alcoholic first as an adjective, then as a noun. Similarly, [Green politics] / [Cary] has become a Green.
[OTOH] a medical practitioner of [psychiatry] is not a psychiatric (better used as an adjective = psychiatric evaluation), but a psychiatrist, a description of a person, not a field. One who enjoys sensual things is a [sensualist] but has an appreciation of the sensual.
