Unit 4: Clarity Filter
Learning Objectives
- Know the five subcategories of clarity errors
- Have practised using the clarity filter
- Be ready to use the clarity filter on your draft papers
Introduction to the Clarity Filter
Errors in clarity affect the reader's understanding of the meaning. The meaning may be lost completely, or the reader may not be able to understand exactly what you mean. Errors of clarity are due to vague or ambiguous language usage.
When checking your draft using the clarity filter, there are five error types to look out for:
- Use of vague expressions
- Lexical ambiguity
- Referential ambiguity
- Syntactic ambiguity
- Garden-path sentences
Introduction to the clarity filter
Use of Vague Expressions
Corpus example: This is something which is XXX from XXX.
The pronoun something is vague, as it can refer to so many different items. Clarity in written English is determined by the specificity of the terminology selected. Indefinite pronouns such as something, someone, or somewhere limit their reference only to a type (thing, person, place) and are rather obscure.
Items can be visualized on a cline from vague to specific:
thing › animal › mammal › dog › poodle › toy poodle
Click each corpus example to see the suggested revision.
Revision: We understood the following aspects about a system...
Aspects is more specific than things and appropriate for describing properties of a system.
Revision: Students point out problems in the presentation...
Replacing the vague pronoun with a specific noun clarifies what is being pointed out.
Revision: When we want to buy a product and estimate its price...
Revision: Looking at Table 4, four features can be seen.
Lexical Ambiguity
Corpus example: It is really high for XXX.
The adverb really has two possible specific meanings: either "to a high degree" (replaceable by very) or "in truth or fact" (replaceable by actually). In the original context it was not possible to determine the intended meaning — this is lexical ambiguity. Additionally, really is rather informal and fails to meet the genre expectations for formality.
Which type of ambiguity arises when a single word has two possible meanings?
Referential Ambiguity
Corpus example: Referring to Smith [10], Jones notes that he...
The third-person pronoun he refers anaphorically to an earlier-mentioned person. However, there are two candidate antecedents (Smith and Jones), which creates confusion. This type of ambiguity also commonly occurs when pronouns such as it and this are used anaphorically.
This ambiguity can be resolved by avoiding the pronoun entirely:
- Jones notes that Smith [10]...
- Smith [10] notes that Jones...
In 'Referring to Smith [10], Jones notes that he...', what causes the ambiguity?
Syntactic Ambiguity
Corpus example: XXX found two AAA and one BBB, which CCC.
The relative clause which CCC may modify only BBB, or it could modify both AAA and BBB. This ambiguity arises from placing a modifier after noun phrases joined by a conjunction. Choose the revision that matches your intended meaning:
Move BBB to the start of the series so the modifier immediately follows it:
XXX found one BBB, which CCC, and two AAA.
Use a distributive determiner (all of which) to make the scope explicit:
XXX found two AAA and one BBB, all of which CCC.
Garden-Path Sentences
Example: The journal plans to publish your paper were just a rumour.
On reading this sentence, most readers will assume plans is a verb. On reaching the finite verb were, they must backtrack and re-read, re-categorizing plans as a noun. Garden-path sentences are not only ambiguous, but the initially assumed meaning is not the intended one.
Garden-path sentences are difficult for writers to notice because the writer is primed to focus on the intended meaning. Second readers and proofreaders can, however, easily notice them because they need to backtrack to figure out the meaning. The challenge is not fixing them once found, but initially identifying them.
The sentence means: The horse that was raced past the barn fell.
On first reading, most people parse "raced" as the main verb. Only on reaching "fell" does it become clear that "raced" is part of a reduced relative clause. This is a classic garden-path sentence.
Disambiguation is usually straightforward once identified. Common strategies include:
- Adding a relative pronoun: The horse that was raced past the barn fell.
- Reordering the sentence to avoid the ambiguous parse
- Replacing a noun that can also function as a verb with a clearer noun
