In Old English the conjugation of verbs was much different than in Modern English. The alphabet was also different. Here is how it might look in Modern English: Present tense Infinitive Loven (to love) Sing......................................Plural 1st person.... love .............. lovath 2nd person... lovest ........... lovath 3rd person ....loveth............ lovath

We were using Germanic forms. The quick answer is: +st for second person singular, ie. using "thou" - this changes the same way as I/me/my/mine, and you'll see the parallels in French, German and Gaelic; and +th for third person singular (in modern English, it is now +s) Dost thou? Knowest thou? (Do you? Do you know/Know you?) Doth he? Knoweth he? (Does he? Does he know/Knows he?) "Yea, he knoweth thee, and what thou dost!"
