You may think you know the words that sit plainly in black on your page. But don't be fooled. Some words are capable of taking on different guises, masquerading as nouns, verbs and adjectives that alter their meanings entirely. This is called lexical ambiguity.
For example: Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo. That may sound like nonsense, but it's actually a grammatically correct sentence. Buffalo is a proper noun, a noun, and a verb. It refers to an animal also know as a bison, an American city, and it can also mean to bully.
In other words, bison from Buffalo that other bison from Buffalo bully. also bully bison from Buffalo. If you let each buffalo perfrom its role, the meaning becomes apparent.
What if the bunch of bullying buffalo decides to cross the ocean? Not just on any ship, but a ship-shipping ship shipping shipping-ship. That sentence sounds just as outrageous, but there's logic to the babble.
Ship can mean a vessel and to transport. When we sub in those meanings, a clearer picture emerges. Here we have a huge ship-carrying vessel transporting ships that themselves are designed to carry goods across the sea.
Lexical ambiguities sail into our speech and writing all the time, spreading confusion and misunderstanding wherever they can-can. You wouldn't necessarily use any of these sentences in a conversation. Becaese they serve as an extreme example on just how tangled everyday language can be.
