Original sentence: The crane truck lifts and moves big heavy things around the building site.
Short answer: The sentence is understandable, but it's a little nicer to write:
- The crane truck lifts and moves big, heavy things around the building site.
Why this is better (explained for a 7-year-old):strong>
- We put a small comma between two describing words like "big" and "heavy" so the sentence is clearer. It is like a tiny pause when you read aloud.
- "Crane truck" or just "crane" are both okay. If you like, you can say "the crane" because cranes lift heavy things.
- "Building site" is fine, but some people say "construction site." Both mean the same place where buildings are being made.
Other good versions:
- The crane lifts and moves big, heavy things around the building site.
- The crane truck lifts and moves large, heavy objects around the construction site.
Pick one you like: I recommend: The crane truck lifts and moves big, heavy things around the building site.
