Punctuate the following sentences You may seat wherevr you laik i had seen a movi yesterdays i believe on him sahu did not understood what you say its amazing

Corrected sentences (punctuation, capitalisation, spelling and grammar):

1. You may sit wherever you like. ("seat" is a noun/transitive verb; "sit" is required.)
2. I saw a movie yesterday. (Capital "I"; with a past time marker "yesterday" the simple past is used, not the past perfect.)
3. I believe in him. (The verb "believe" takes the preposition "in".)
4. Sahu did not understand what you said. (After "did not" the base form "understand" is used; reported verb in the past.)
5. It's amazing! ("It's" = it is, needs an apostrophe; exclamation mark for the exclamatory sentence.)
