The 4 C's of Effective Writing
Effective writing in academic, journalistic, and professional settings demonstrates four primary virtues. It is clear, concrete, concise and correct. The table below details my shorthand marginalia (written in the margins of your papers), indicating the need for revision in these areas.
| Virtue | Marginalia | Description |
|---|---|---|
| Clear | CL | Clear writing is straightforward, avoiding convoluted phrases or over-long sentences. It favors sentences written in active voice. |
| Concrete | CC | Concrete writing is specific and values the tangible. It uses the most precise word available in any given situation. |
| Concise | CN | Concise writing packs the most meaning into the fewest words. Concise sentences rarely depend on forms of "to be" like "is" and "are." |
| Correct | CR | Correct grammar, mechanics, and format are baseline expectations for writing in any professional field, particularly in media-related industries. Perfection is the standard. |
Other Marginalia

- A check mark next to a passage indicates excellent work. Occasionally, I'll combine this with other marginalia. A check mark combined with "CC," for example, indicates that this passage demonstrates excellent concreteness.
- APOS
- Apostrophe error
- CS
- Comma splice
- DM
- Dangling modifier
- Frag
- Sentence fragment
- Org
- This indicates a problem with organization, either in the development of a paragraph or in the sequencing of a larger section.
- Plag
- Plagiarism. Far too many college students do not understand plagiarism well enough to avoid committing academic fraud. There is no excuse for this, since every writer's handbook covers plagiarism in depth.
- MLA
- Use the formatting standards codified by the Modern Language Association. These are presented in any writing handbook.

- MS
- Mixed sentence construction
- PN
- Pronoun error
- VF
- Verb form
- VT
- Verb tense
