NO ONE knows how to use thou/thee/thy/thine and i need to see that change if ur going to keep making “talking like a medieval peasant” jokes. /lh

They play the same roles as I/me/my/mine. In modern english, we use “you” for both the subject and the direct object/object of preposition/etc, so it’s difficult to compare “thou” to “you”.

So the trick is this: if you are trying to turn something Olde, first turn every “you” into first-person and then replace it like so:

“I” →  “thou”

“Me” →  “thee”

“My” →  “thy”

“Mine” →  “thine”

Let’s suppose we had the sentences “You have a cow. He gave it to you. It is your cow. The cow is yours”.

We could first imagine it in the first person-

“I have a cow. He gave it to me. It is my cow. The cow is mine”.

And then replace it-

“Thou hast a cow. He gave it to thee. It is thy cow. The cow is thine.”

This is perfect and the only thing missing is that when “thy” comes before a vowel it’s replaced by “thine”, i.e. “thy nose” but “thine eyes.” English used to do this with my and mine too (and still does with a and an).

The second person singular verb ending is -(e)st. In the present tense, it works more or less like the third person singular ending, -s: 

The -(e)st ending is only added to one word in a compound verb. This is where a lot of people make mistakes:

NOT

If you’re not sure, try saying it in the third person and replacing the -(e)st with -s:

In general, if there’s one auxiliary, it takes the -(e)st ending) and the main verb does not. If there are multiple auxiliaries, only one of them takes -(e)st:

You can reduce the full -est ending to -st in poetry, if you need to drop a syllable:

In some common words–mostly auxiliary verbs, or what you might have learned as “helping verbs”–the ending is always reduced:

Sometimes this reduction takes the last consonant of the stem with it:

Or reduces the -st down to -t:

However! UNLIKE the third-person singular -s, the second person -(e)st is ALSO added to PAST TENSE words, either to the past stem in strong (irregular) verbs or AFTER THE -ed in weak (regular) verbs: 

This is different from the third person!

It’s not wrong to add -(e)st to a long Latinate verb in the past tense, but it’s unusual; it’s much more common to use a helping verb instead:

And a couple last things:

1.) Third-person -(e)th is mostly equivalent to and interchangeable with third-person -s:

HOWEVER! Third-person -(e)th, unlike -s but like -(e)st, can, sometimes, go on STRONG past-tense verbs:

This never happens with weak verbs:

And even with strong verbs, from Early Modern (e.g., Shakespearean) English onward, it’s quite rare. But you will see it from time to time.

2.) In contemporary Modern English, we invert the order of subjects and auxiliary verbs in questions:

If there’s no auxiliary, we add one–do–and invert that:

In Early Modern English, this process was optional, and mostly used for emphasis; all verbs could be and were moved to the front of the sentence in questions:

Do-support was also optional for negatives:

3.) Imperative verbs never take endings:

4.) Singular ‘you’–that is, calling a singular person by a plural pronoun–arose as a politeness marker; and ‘thou’ fell out of use because it eventually came to be seen as impolite in almost all contexts. In general, once singular ‘you’ comes into use, it is used for addressing

‘Thou’ is used for

It is safer to ‘you’ someone who doesn’t necessarily warrant ‘you’ than to ‘thou’ someone who does.

5.) And finally, that ‘ye’? That’s the nominative form of you–the one that’s equivalent to ‘I’ or ‘we.’ 

Any time you’re using ‘thou’ for the singular, the second person plural– ‘y’all’– declines like this:
