The following example sounds very choppy
when read aloud…
I go to St. Lawrence University. I am a sophomore. I am 19
years old.
I am a 19-year-old sophomore at St. Lawrence
University.
If your writing looks and reads like this
you may want to consider combining sentences.
![]()
Use Punctuation
Be careful not to use commas to combine
sentences. This may create run-on
sentences and comma splices.
There are 3
punctuation marks that are stronger than a comma but weaker than a period,
question mark, or exclamation point. These are the dash (--), colon (:), and
semi-colon (;).
-- A dash is used to add more information about some
part of your sentence. It is very
informal, so it may be advisable not to include it in your writing.
: A colon is used to add more information or to give
examples in your sentence.
For example: He plays many sports: soccer, hockey,
and basketball. (Instead of: He plays
soccer. He plays hockey. He plays basketball).
; A semi-colon is the most important punctuation mark for combining sentences, it is used to connect clauses. It can also be used to connect clauses together with linking words such as however, moreover, and therefore. Remember that it is the semi-colon and not the conjunctive adverb that connects the clauses.
Use coordinating words
The coordinating conjunctions are as follows.
“and” is used
to join clauses that contain additional information
(I bought a
ticket and I got on the bus).
“or” is used
to join clauses that contain choices or alternatives
(Write me a
letter or send an e-mail message).
“but” is used
to join clauses that contain opposing ideas
(I arrived
early but no one was there).
“so” is used
to join clauses that contain ideas of cause and effect
(The jacket
didn't fit so I took it back to the store).
“for” shows logical consequence; it has the same meaning as because, the reason why
(Coping with
environmental issues is a necessary part of industrial studies, for industries
affect the environment).
“nor” shows
addition of a negative point
(The
environment cannot sustain constant resource depletion, nor can it recover
quickly from wide-scale resource extraction).
“yet” shows
contrast
(More
secondary schools are implementing programs designed to increase teenagers'
awareness of the dangers of drinking and driving, yet alcohol-related traffic
accidents continue to be one of the leading causes of death for people between
the ages of fifteen and twenty-two).
¨ APPOSITION: In apposition, a word or phrase is taken and placed in a parallel position to a noun in the sentence. An appositive is like a parenthetical statement surrounded not by parentheses but by commas.
(Jason is a very good student.
He always does his homework. Jason, a very good student, always does his
homework).
