Usage notes
• Many style guides and many gay people recommend against the use of the word "homosexual" because of its clinical and sometimes pejorative connotations, preferring the terms gay and (for women) lesbian, and relationship descriptors like "same-sex relationship". Many consider it particularly pejorative when it is used as a noun, and prefer "gay man", "gay woman" (or "lesbian").
• The first part of the word derives from the Greek word for "same", which is traditionally pronounced /ˈhɒməʊ/, unlike the Latin word homo (“man, human being”), which is pronounced /ˈhəʊməʊ/ (RP). However, it is much more common to pronounce the first vowel as /əʊ/ (RP) / /oʊ/ (US) than as /ɒ/.
