EXAMPLE
“… I will, your worship: but I am glad his honour, the Major, is not to be jocum tenus for your worship, he’s so much upon the roguish order with the women, now and ten. I did not care to mention it to your worship before; but as true as I’m alive he was a little rombustical to our Bridget, no longer ago than last Sunday was se’night, as she was coming home from church. …”
