Ok:
I start with a bit of an introduction - like mine would be Williams presents the theme of ..... by ....
So basically include the theme or whatever the question is based on and explain why you think that
Next paragraph i would include would be context, so talk about what happened BEFORE the extract involved and AFTER but make sure you think this back to the question so if the theme is death, include context that happened before the extract involving death, and the same for afterwards
Then include your paragraphs about the linguistic, literary and rhetorical devices, BUT start each paragraph with a dramatic effect that highlights it. For example you could say ' Williams shows pathos within the audience to allude to pity for Blanche as.... the hyphens used suggest her slipping of her mental state....
So start the paragrahy with a dramtic device and then start to include on of your three devices. If you explain each well and give evidence for your findings and LINK BACK to your theme or main question you should be fine!
Im sorry if its not very well exlpained plus i have explained it in the context of streetcar as im not doing Hamlet sorry. I hope it helps
