English is pretty confusing---even to a native speaker. Tell us sentences that are confusing and (somehow) grammatically correct. Maybe even help explain why it means what it means. You can share the sentence found in a book, someone has said, or by searching online.
Here's one: Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo. Sounds confusing, but it is grammatically correct. I don't know how to explain so here's info from a website: Simplified parse tree S = sentence NP = noun phrase RC = relative clause VP = verb phrase PN = proper noun N = noun V = verb "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" is a grammatically correct sentence in English, often presented as an example of how homonyms and homophones can be used to create complicated linguistic constructs through lexical ambiguity. It has been discussed in literature in various forms since 1967, when it appeared in Dmitri Borgmann's Beyond Language: Adventures in Word and Thought. The sentence employs three distinct meanings of the word buffalo: as an adjectival proper noun to refer to a specific place named Buffalo, the city of Buffalo, New York, being the most notable; as a verb to buffalo, meaning (in American English[1]) "to bully, harass, or intimidate" or "to baffle"; and as a noun to refer to the animal, bison (often called buffalo in North America). The plural is also buffalo. A semantically equivalent form preserving the original word order is: "Buffalo bison that other Buffalo bison bully also bully Buffalo bison." From wikipedia.

Was this parodied in 'Walk Hard: the Dewey Cox Story'? After Dewey cuts his brother in half accidentally: "You ain't half the boy Nate was! You ain't even half the boy that the top half of Nate was after you cut him in half!" "So you're saying that I'm less than a quarter of the boy Nate was?" "The wrong kid died!"
