Basic Grammar
Here is a list of major grammar issues students have problems with. Refer to this “cheat sheet” in this and future
writing-intensive classes to guide you!
Independent Clauses / Complete Sentences
An independent clause is a complete sentence. Think about it as being independent, not requiring anything else
to complete it. An independent clause has both a subject and a predicate.
Ex:
The meeting began at 4:00 a.m.
Subject:
The meeting
Predicate:
began
(the doer of the action—who/what is doing the action)
(the action)
Dependent Clauses / Sentence Fragments / Incomplete Sentences
A dependent clause is an incomplete sentence—often referred to as a fragment. Think about it as depending on
something else to complete it. A dependent clause often starts with one of the FANBOYS or another
coordinating word like because, since, therefore, etc.
for
and
nor
but
or
yet

A
N

S
Ex:
And then I went home.
So I wanted more.
Because I was hurrying.
Since she thought I had lied.
Run-on Sentences
A run-on is two or more complete sentences (independent clauses) strung together without punctuation or with
the incorrect punctuation (i.e., commas  comma splices)
Ex:
So I went to the store then bought some bread I also got some cheese.
Most of us were taking the same classes, if someone had a question, we would all help out.
Colons
Use a colon to join an independent clause (complete sentence) and a list.
Correct:
He bought three posters to decorate his apartment: an old concert poster, a view of the
city, and a mural of San Diego.
Incorrect:
Volunteers aid biologists in: erosion control, trail maintenance, and clean-up.
Incorrect:
Jessica’s wardrobe included: three pairs of pants, a nice skirt, and a party dress.

Semi-colons
There must be a complete sentence on both sides of the semicolon!
Correct:
Incorrect:
Police want to crack down on drug use at raves; they have started to arrest more people.
Internet retailers have a limited customer base; only those with Internet access.
If you have a conjunction after the semi-colon, you need a comma.
Correct:
Incorrect:
Police want to crack down on drug use at raves; thus, they have started to arrest more
people.
There were several people I wanted to see at the party; however I didn’t see any of them
there.

Commas
Commas often are subjective—they depend on the preference of the reader or the style guide for the audience
you’re writing to.
1. Use a comma after an introductory phrase like however, therefore, nonetheless, finally, for example
a. For example, you would use a comma in this sentence.
2. Use a comma for phrases that you could take out of the sentence but still retain the overall meaning
a. A comma, however, would definitely go here.
3. Depending on your style guide, use the “Oxford comma”: the optional comma before the “and” at the
end of a list
a. I bought a shirt, a pair of pants, and a jacket.
4. Use a comma with dates and places
a. I first joined Monday, May 5, 2003.
b. I was born in St. Louis, Missouri, a city in the Midwest.
5. Use a comma with brief interjections
a. Have some coffee, won’t you?
b. She said, no, she wouldn’t be having any coffee, thanks.
Hyphens
Add a hyphen for a compound modifier (more than one adjective strung together) before a noun:
The sixteen-year-old girl was a well-known celebrity.
FLC Writing Program / Writing Conventions
Do not add a hyphen if the modifier comes after the noun:
She was sixteen years old. The celebrity was well known.
Being Verbs
Aim to cut as many as possible: be, being, been, is, was, were, am, are
A Final Note…
Remember that many of these “rules” are dependent on audience! Plus, there is a well-established precedent of
breaking the rules for effect. For example, e e cummings’ poetry plays with fragments, parentheses, commas,
etc… The difference is, however, that these rule-breakers are often prose and poetry writers, while you are
writing technical materials for a lay audience. What this means is that you must look at your document and
decide whether it is appropriate to focus on strict grammar conventions (likely) or play with form and style
(maybe not). Readers make assumptions about the authors of the documents because of errors. Sentence
fragments, misspellings, and the like resulted in a visual picture of the author as uneducated, careless, lazy, etc.
Thus, one of the best things you can do as a technical writer is to pay attention to your work!
