Choosing a Dictionary Entry for an Ambiguous Word
A student is reading a short editorial about urban planning and hits this sentence: "The council's plan will sanction new construction along the river, provided the developer covers flood-mitigation costs." The student looks up sanction and finds two seemingly opposite senses: (1) to give official approval or authorization; (2) a penalty or coercive measure, often used in the plural. The student concludes the sentence is contradictory and asks you which meaning is correct. The surrounding paragraph discusses permits, zoning exceptions, and a developer's obligations. Later in the same article appears: "Critics warned that the new fees would sanction homeowners who delay repairs."
1. Explain how to determine the correct sense of *sanction* in the first sentence, using context rather than the dictionary alone.

Use contextual and grammatical cues, not the alphabetical order of senses.
- Grammar: in the first sentence, sanction is a verb followed by a direct object, "new construction," and modified by "will." The noun sense (a penalty) does not fit a verb-plus-object frame here as naturally as the approval sense does.
- Collocates: the sentence contains "provided the developer covers..." - a conditional permission structure. Permission language ("provided," "will allow") points to sense (1), approval.
- Topical frame: the paragraph is about permits and zoning exceptions, i.e., the machinery of official authorization. Nothing in it describes punishment.
So the first sentence means "officially approve." The student's confusion is reasonable - sanction is a contronym, a word with two opposite senses - but context disambiguates it. A useful habit: check whether the word is functioning as a verb or a noun, then check whether the surrounding words describe permission or punishment.
2. The second sentence uses *sanction* differently. Analyze it and explain what a reader must notice.

In "the new fees would sanction homeowners who delay repairs," the subject is "fees" and the object is people. Fees do not grant approval to homeowners; they impose a burden. The phrase "who delay repairs" identifies people being penalized. The intended sense is therefore closer to penalize - a verb use derived from the noun sense (2).
What a reader must notice:
- The subject changed from a governing body (which can authorize) to a financial instrument (which can penalize).
- The object changed from an activity (construction) to people (homeowners).
This is a good illustration that a word can shift sense within a single text. Skilled readers do not fix a meaning at first encounter; they re-evaluate when the grammatical frame changes. Note also that this second use is less standard and can confuse readers, which is worth discussing as a style issue.
3. The student asks, "So how do I know which meaning a dictionary lists first?" How do you answer, and what study habit do you recommend?

Answer: dictionary order is not a reliable guide to which sense is intended. Some dictionaries order senses by frequency, some by historical development, and some by logical grouping. Frequency order reflects general usage, not the usage in front of you. For contronyms like sanction, cleave, oversight, or dust, the listing order tells you almost nothing about a specific sentence.
Recommended habit: the "frame first, dictionary second" routine.
- Before looking anything up, ask what part of speech the sentence requires and what the surrounding words suggest.
- Look up the word and read all the senses, not just the first.
- Select the sense that fits the frame, then reread the sentence with that sense substituted to confirm it makes sense.
A short practice set of contronyms in context builds this habit quickly and teaches students that dictionary consultation is an act of matching, not of retrieval.
