Carol earlier:

pointing out that it's "didst thou" ("thee" is objective case; "thou"
is nominative case).

> I hope you'll forgive me for pointing out that surely "thee" - which
I agree is referring to an object - is however actually the accusative
case.

Carol responds:
Possibly you're thinking of Latin. English doesn't have an accusative
case; the English cases are subjective (corresponds to nominative),
objective (corresponds to accusative), and possessive (corresponds to
genitive). And, of course, we use prepositions to indicate the
relationships expressed through the dative and ablative cases in
Latin, so those cases have no English equivalent.

>From Merriam-Webster:

Main Entry:
    thee 
Pronunciation:
    \th\
Function:
    pronoun 

archaic objective case of thou
1 a—used especially in ecclesiastical or literary language and by
Friends especially among themselves in contexts where the objective
case form would be expected b—used by Friends especially among
themselves in contexts where the subjective case form would be
expected 2: thyself

>From an online English grammar site:

"Grammar Handbook: Noun and Pronoun Case

"Case refers to how nouns and pronouns are used in relation to the
other words in a sentence. The three cases are subjective, objective,
and possessive. See below for a chart of pronoun cases."

The site also notes that subjective case is sometimes called
nominative case (which excuses my own little slip with "thou" <smile>)
but it says nothing about objective case (in English) ever being
called accusative case.
