Cranes and other kinds of equipment
This huge crane is at a building site in San Francisco. You may think of cranes as modern pieces of equipment, but they are not. The Greeks invented cranes more than twenty-five hundred years ago.
Huge: big, large
Site: a place, a location
Invented: created, developed
One of the most common mistakes we see is equipment. What is the plural of equipment? Equipment has no plural form.
If you are talking about one crane, you would say this: We need one crane. We need one piece of equipment for the job.
If you are talking about two cranes, you would say this: We need two cranes. We need two pieces of equipment for the job.
