what is the origin of the word sex.?

Answer 1

Sex, of course, can mean many things, but the etymology of this top search term is elusive. The word sex first appeared in English in the 14th century, adopted from Old French sexe, in turn from Latin sexus, a derivative of the verb secare 'to cut'. The relation of sex to cut is that the human race is "cut" or separated into two genders.

Answer 2

Via Middle English and Old French, from Latin sexus.

Answer 3

S - soul
E - eternal
X - xylose

This is my personal opinion, because it concerns what is supposed to be eternal, our soul and "xylose" ( essence).
