Sir can you please clarify my doubt of these rules 1. When the vocative is stressed we have to use exclamation mark For eg: Fool! By thee my plan's spoiled ( Over here, which one is the example sir in this given example of vocative ?) 2. When to use commas after adverbial phrases formed by absolute Constructions Eg- The weather being very hot , we decided to go for shopping. ( Which one is the adverbial phrase here ?) 3. To separate,words,phrases or clauses inserted into the body of a sentence. Eg- The principal ,too, was partly responsible. She did not, however,get her lost ring back. Some college students behaviour, to say the least, was very rude that day. ( In this example which all are the phrases and clauses ?) Eg-2 The teachers , who were well trained were awarded. ( Which one is the clause over here sir and phrases ?) 3. To avoid the repetition of a verb Eg - She will win,you ,never. ( Where is the verb over here sir?) - I gave her my book, and him ,a pen.( Where is the verb) 4. To separate a subordinate clause that comes before the principal main clause Eg- If you practice grammar daily, you will be perfected. When I was a student, I practiced grammar daily.( Where is the subordinate clause over here sir ?) 5. Two separate short coordinate clauses of a compound sentences Eg- I came, I saw, I conquered.(where is the coordinate and compound clause in the sentences ?) Eg- He joined, learned and won the job.( Where is the coordinate clause and compound clause in this sentence?) Eg- Men may come, and men may go, but I go on forever. (( Where is the coordinate clause and compound clause in this sentence?) Sir kindly clarify my doubts as early as possible and it would be a great help if you do so ?
