For our "Colon" (:) assignment, my teacher asked us to create a compound sentence that makes a general statement and follows with specific details/ create expectations and fulfills it. But How do you do that using Colons?.. A simple example would help me out. Much appreciated.

Can someone break this down because these examples are not helpful

From the above site:

"Use a colon [ : ] before a list or an explanation that is preceded by a clause that can stand by itself. Think of the colon as a gate, inviting one to go on:

There is only one thing left to do now: confess while you still have time.
The charter review committee now includes the following people:
the mayor
the chief of police
the fire chief
the chair of the town council"

I understand using colons when having a list, but I think my teacher is saying to combine 2 Compound Sentences using a colon but the sentences are general statements and follows with specific details or creates expectations and fulfills it. Idk of an example that would be best as far as 2 compound sentences and the following things asked of my teacher.. thankyou for the list but I get that part

Compound sentences are joined by semi-colons, not colons.

My brother likes living at the lake; I prefer to live in town.

Then it doesn't make sense if my teacher is saying to "Create compound sentences that make a general statement and follows with specific details/ create expectation and fulfill it."

Of course compound sentences are joined by a Semi-Colon

Sorry to be confusing. I apologize; however, my teacher is a top notch teacher but this still doesn't make sense

This site clarifies this question.

Please check with your teacher to see if there's a communication problem.

Alright. Thankyou so much for the best possible help. I'll be sure to do that.

You're very welcome.
