Construction grammar is like building with Legos. Just like we use different shapes and colors of Legos to build different things, we use different grammatical structures or parts of words to build sentences that mean different things.
For example, just like a Lego block can be used as the foundation for a castle, a verb like "run" can be the foundation for a sentence like "I run to the store" or "They run every morning."
Construction grammar looks at how we put these different building blocks together to create meaning in language. So just like we can use different combinations of Legos to build different things, we can use different combinations of grammar and words to create different sentences that mean different things.
Construction grammar helps us understand how we use language to communicate and express our thoughts and ideas.
