Coitarche is a term used to describe a female's first time experiencing sexual intercourse. It is believed to originate from the Greek words "koitē" meaning "bed" and "arkhē" meaning "beginning" or "commencement". Its spelling can be explained using IPA phonetic transcription as /kɔɪtɑːkiː/ with stress on the second syllable. The 'c' is pronounced as a hard 'k', and the 'ch' as 'k' followed by 'ee'. The 'a' in the first syllable is pronounced as 'o'.
