One of my characters is 21 and younger is 16. The older guy comes from a wealthy landowning family and the young man from a Suffolk farming family.
I have searched Google, Wikapedia, 16th century dictionaries on line, Yahoo and Various other sites for 16th century terms and language usage but I cannot find anything specific. Only terms used between men and women or parent to child. I have used the terms as above in the subject field using different variations as in 16th century terms of endearment/affection between men, male lovers, homosexual men.
I hope you can help.
