Common Form Errors

The following are deviations from standard academic English commonly encountered in student writing.

Proper vs. Common Nouns

Proper nouns refer to specific things and are capitalized (CMS 8.1).

Common nouns refer to things in general and are not capitalized.

Solution

  2. Whistle While You Work
  3. A Little Learning Is a Dangerous Thing
  4. Progress in In Vitro Fertilization
  5. Sitting on the Floor in an Empty Room

Capitalization of Geographical Terms

Compass directions (north, south, east, west, etc.) are lower case (CMS 8.46), unless they are part of a proper name (e.g. North Carolina, Eastern Illinois University) or denote specific regions of the world or a country (the Far East) (CMS 8.47).

Specific regions of the world or of a particular country are often capitalized (South Asia, Southern California). However, general locations within a specific area (e.g. central Illinois) are often lower case. CMS provides a list of examples, but defers to Webster's for other specific cases, and also defers to authors when they have strong preferences (CMS 8.47).

CMS arbitrarily specifies that "the equator" and the adjective "equatorial" (when not used in a proper name like Equatorial Guinea or Equatorial Current) should be lower case. But as with capitalizations of regions in general, CMS indicates that "that an author’s strong preference should usually be respected" (CMS 8.47).

"In nontechnical contexts, the word 'earth,' in the sense of our planet, is usually lowercased when preceded by 'the' or in such idioms as 'down to earth' or 'move heaven and earth.' When used as the proper name of our planet, especially in context with other planets, it is capitalized and 'the' is usually omitted" (CMS 8.140).

The word "geography" when referring to an academic subject is not capitalized unless used as part of a department or course name (CMS 8.85, 8.86).

"Entities that appear on maps are always capitalized, as are adjectives and nouns derived from them. An initial the as part of a name is lowercased in running text, except in the rare case of an initial the in the name of a city" (Californian, the North Pole, South China Sea) (CMS 8.45).

Complete Sentence

A clause is a grammatical unit that contains a subject, a finite verb, and any complements that the verb requires. An independent clause can stand alone as a sentence (CMS 5.225).

The four traditional types of sentence structures specified in CMS each have at least one independent clause (CMS 5.217).

A sentence fragment is "a part of a sentence punctuated as if it were a complete sentence. It is a group of words that begins with a capital letter and ends with a period, exclamation point, or a question mark, but does not express a complete thought" (University of Illinois Writer's Workshop 2017).

Phrases, such as lists of items or word definitions that are not complete clauses, are not complete sentences and should not have trailing punctuation, or they can be considered sentence fragments.

Problem

  1. Human, physical, and GIS.
  2. Before 9am each Friday morning.
  3. Statistical data relating to the population and particular groups within it.
  4. A year-round botanical garden with more than 4,000 plant species in 30 themed gardens.
  5. Breathtaking volcanic landscapes, former home of the Pueblo people.

Solution

  1. The three primary domains of geography are human, physical, and GIS.
  2. Weekly assignments in this class should be completed before 9am each Friday morning.
  3. Demographics are "statistical data relating to the population and particular groups within it."
  4. This year-round botanical garden features more than 4,000 plant species in 30 themed gardens.
  5. Former home of the Pueblo people, these 33,677 acres feature the most breathtaking volcanic landscapes.

Punctuation Goes Inside Closing Parentheses

In the United States, when using punctuation following quoted text, the punctuation goes inside the closing quotation mark. This seemingly illogical practice (which is not used in Britain) dates from a time when fonts used for printing had fixed-width characters, and placing the punctuation after the quotation mark created an unattractive gap between the end of the text and the punctuation (MLA Style Center 2020, CMS 6.9).

However, when providing a parenthetical citation at the end, the citation is part of the sentence and the closing punctuation follows the citation.

Problem

  1. The Tuskeegee Syphilis Study violated the ethical principle of "respect for persons" because the test subjects were not given the opportunity to give "informed consent".
  2. The variable name is "Arthritis Prevalence Percent", and it represents the percentage of the total population that has arthritis.
  3. Longitude is "angular distance measured on a great circle of reference from the intersection of the adopted zero meridian with this reference circle to the similar intersection of the meridian passing through the object." (Merriam-Webster 2021)

Problem

Solution

The Oxford Comma

The Oxford comma (or serial comma) is a comma used before the final conjunction in a list of items: X, Y, and Z.

The Chicago Manual of Style has recommended use of the Oxford comma since 1906, although it is considered optional (Chicago Manual of Style 2017).

The Oxford comma was pivotal in a notable legal case in Maine involving overtime pay for union drivers that cost their company $5 million (Victor 2018).

Problem

  1. The three domains of geography are human geography, physical geography and GIS.
  2. Maine law requires time-and-a-half pay for each hour worked after 40 hours, but carves out exemptions for, "The canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of: (1) Agricultural produce; (2) Meat and fish products; and (3) Perishable foods."

Energy Unit Abbreviations

The following are examples of capitalization for some common energy units that follow the CMS on miscellaneous technical abbreviations (CMS 10.49) and SI prefixes (CMS 10.56).

AbbreviationUnit
JJoule (named for English physicist James Prescott Joule)
BtuBritish thermal unit
kWkilowatt (named for Scottish inventor James Watt)
kWhkilowatt-hour
mWhmilliwatt-hour
MWhmegawatt-hour
GWhgigawatt-hour
TWhterawatt-hour

Possessive vs. Plural

For most nouns, adding an apostrophe and an 's' makes it possessive meaning it becomes an adjective describing ownership of another noun: John's Manhattan apartment is tiny.

Simply adding an 's' with no apostrophe makes a singular noun plural, meaning that the noun represents multiple things: Manhattan apartments are usually tiny.

The exception to this general rule is its vs. it's:

  1. its is possessive: John's apartment building is new and its lobby is quite impressive.
  2. it's is a contraction for it is: It's hard to find a cheap apartment in Manhattan.

A missing apostrophe figured in a notable defamation case in Australia (Albeck-Ripka 2021).

Cite vs. Quote

The word cite (short for citation) is commonly misheard and misspelled as site.
