Dear Principal Mirumbi;
Please excuse Ajaja from school next week. He will be joining me on a tour of the Congo River. I am confident he will keep up with his school work, he has already written a schedule for studying during the trip.
Our plan is to make a film documentary about three natural wonders of the Congo; Boyoma Falls, Malebo Pool, and the great cataracts above Matadi. Ajaja has already come up with a name for the film. He calls it On the Congo, Adventures of the World-Renowned Naturalist Ajaja Olatunji. I am sure his classmates will enjoy viewing the film after we return.
- The Colon -
Our opening paragraph shows another place to use a colon:
He calls it On the Congo, Adventures of the World-Renowned Naturalist Ajaja Olatunji.
We should always use a colon to separate a title from a subtitle:
He calls it On the Congo: Adventures of the World-Renowned Naturalist Ajaja Olatunji.
- Other uses of the colon -
The colon can also be used to introduce a word or expression when the colon substitutes for the phrase as a result:
The camera worked flawlessly: the film was a success.
Another use of the colon is to formally introduce a quote:
The beauty of the river reminded Ajaja of a statement by his father: "I can imagine, therefore I can be more."
In a notation of time, separate hours from minutes with a colon:
We arrived at Boyoma Falls at 10:30 A.M.
When we identify a chapter and verse from scripture we also use a colon:
When Ajaja saw how abundantly the Congo watered the plains of Africa, he remembered Genesis 13:10 and quoted Lot: "It is like the Garden of the Lord."
