Clauses highly improve sentence structures. They can make the sentence sound a lot better to the tongue, and it even make the sentence easier to understand. I hope this helps! :)
Sarcasm is an ironic or satirical remark tempered by humor. Mainly, people use it to say the opposite of what's true to make someone look or feel foolish. For example, let's say you see someone struggling to open a door and you ask them, "Do you want help?" If they reply by saying, "No thanks. I'm really enjoying the challenge," you'll know they're being sarcastic. Sarcasm is all about the context and tone of voice, which is why it works better verbally. It's something you'll know when you hear it.
You must look at the pattern of rhymes. For example
Monday's child is fair of face, A
Tuesday's child is full of grace,A
Wednesday's child is full of woe,B
Thursday's child has far to go,B
Friday's child is loving and giving,C
Saturday's child works hard for his living. C
And the child that is born on the Sabbath day D
Is bonny and blithe, and good and gay. D
so it is AABBCCDD
So just look for that! But, if you gave us the poem we could help!
