Here are some errors to avoid in writing, listed by the codes I use to identify them on student papers, and illustrated by examples from actual student papers to go with them. There are also links for places to find help.

The following stresses certain technicalities of writing that all college students should master. Making mistakes on these kinds of things has a way of instantly undermining the credibility of any professional writing. If you haven't had to learn basic rules like these, now is the time!

That said, the most fundamental part of writing is not these technicalities, but the task of making sense with words. If you cannot write clearly on your topic, you probably have not thought clearly on it. Ultimately composition is an extended process that depends essentially on discussion and revision. I strongly encourage you to take advantage of Western's Writing Center, including their Writer's Resources on the web, to improve your writing abilities.

Note: abbreviations below in capitals are codes I use in marking up papers.

INF: language is too casual or INFormal for academic writing (Note: This does NOT mean it is okay be jargony, stodgy, or pretentious - just simple and direct!)

SP: SPelling problem
When in doubt about the spelling of a word, use a good dictionary. At a bare minimum, use an electronic spell-checker -- but be aware it will not detect words that are spelled correctly but are the wrong choice (i.e., their and there). Either way, make an effort to memorize the correct spelling. See also the Writing Center list of "prejudicial" mispellings.

P: Punctuation
The problem here may be your use of a comma, period, colon, semi-colon, hyphen, quote mark, apostrophe or other marker.  See the Writing Center links for Punctuation (near bottom of page to which this links).

AWK: AWKwardly constructed sentence or phrase
- often because of several other contributory problems.

Wavy underlining, or circles around words
Sometimes these marks are accompanied by explanations, but sometimes I use them alone. They indicate a problem which I'm leaving to you to diagnose and correct. The problem might include any of the above-mentioned difficulties, or others.

A common problem is mis-use of the apostrophe -- see Writing Center for help on apostrophe use
