Salutations to all during this tragic time where all feels quite, quite down, Firstly I hope all are well.
Now, onward to my question: I have, for the past half-year or so writ a play based in London 1660s--It is a period piece and my distinct and wrathful convictions to historical accuracy are most vicious, to say the least--now, I have thoroughly studied the time period (period documentation and poetry writ during the time) and regardless I have quite an obsession with Shakespeare and Milton, so in other words, I am rather decently rooted into the overall essence of writing in the period's "feel"--but it has come to the point where I am looking for just a simple rulebook that gives the important grammatical rules for the period: so, for example, when to use the root -th (riseth, giveth), distinctly how to follow words such as "thou," "thy", etc. with (thou wouldst, thou couldst)--so on and so forth--
I would like to go over the play and check the rules to see if everything is as "correct" as it may be. Any sort of "collected guide to the period's rules" would be extraordinarily appreciated.
