[00:00.83]Hi there, thanks for your question.
[00:02.77]This is a really interesting one.
[00:05.24]In some very old forms of English you will see these type of words,
[00:08.59]thou, giveth, hast etc,
[00:12.45]most notably in certain religious texts such as The Bible or possibly English translations of The Qur'an.
[00:19.12]In other words,
[00:20.87]these forms are what we call archaic,
[00:22.88]meaning they're not in active use anymore,
[00:25.47]other than in either religious or ancient texts,
[00:28.52]or as they appear in literature and other forms of writing from previous centuries.
[00:33.06]A specialist in the development and history of English would perhaps be able to tell you more about the origins and the use of the specific words in your example,
[00:42.15]but most of them would have been in use from around the 15th century onwards in a form now known by academics as Early Modern English.
[00:50.00]Although this was by no means used consistently if one examines different texts from the time,
[00:56.08]by about the 18th century these forms were not so widely used and I can clarify that nowadays we would definitely not see or hear these in typical situations,
[01:05.81]spoken or written.
[01:07.12]In today's English, thou would always be replaced with you,
[01:10.53]for example,
[01:12.16]seest with see and so on.
