gyna

Gyna is a combining form used in medical and scientific terminology to denote relation to women or the female sex. It derives from the Greek gyne (γυνή), meaning woman. In English, the form appears as gyna-, gyn-, or gyne- depending on the word and dialect.

It is most visible in terms related to female health and reproduction. For example, gynaecology (UK spelling) or gynecology (US spelling) is the branch of medicine dealing with women's health; a gynaecologist or gynecologist is a physician who specializes in this area; gynaecological is the corresponding adjective. Other related terms include gynaecomastia, the enlargement of male breast tissue (British spelling gynaecomastia; American gynecomastia); gynophobia, fear of women; and gynocentric, relating to or centered on women.

As a prefix, gyna- is used to form a wide range of terms and does not stand as a standalone word in English. It appears across medical, biological, and social terminology to discuss topics related to women, gender, or female anatomy. Spelling varies by style guide, with gyna-, gyn-, or gyne- used in different words and varieties of English.
