intersexual

The term 'intersexual' is a modern scientific compound, formed in the early 20th century by combining the Latin prefix 'inter-' (between) with the adjective 'sexual' (pertaining to biological sex). The prefix 'inter-' derives from the Proto-Indo-European root enter- (between, among), which is also the source of Latin 'inter' and English words like 'interact' and 'interval'. The word 'sexual' traces back to Latin 'sexus', likely from 'secare' (to cut, divide), reflecting the concept of division into male and female. Thus, the literal construction "between the sexes" logically evolved to describe phenomena occurring between males and females, and more specifically, to denote individuals whose biological anatomy does not fit typical binary definitions of male or female.

Structure: inter (between) + sexual (relating to sex) - inter: Latin origin, meaning "between, among". A prefix indicating reciprocal action or location. - sexual: From Latin sexualis, from sexus (sex). An adjective-forming suffix indicating relation or pertaining to.
