Look out for words in a funny order
1. Another reason Shakespeare can be tricky to understand is the long complicated sentences
2. It's hard because the words are in a funny order. If you change the order it makes it easier to understand. For example:
"So foul and fair a day I have not seen." --> I have not seen so foul and fair a day
"O, full of scorpions is my mind, dear wife!" --> O, my mind is full of scorpions, dear wife!
