Donnellan's Referential-Attributive Distinction says a definite description can be used either referentially, to pick out a particular person, or attributively, to describe whoever fits it. In Formal Logic I, it shows why the same phrase can work differently in argument analysis.
Donnellan's Referential-Attributive Distinction is the idea that a definite description like “the man drinking a martini” can be used in two different ways in Formal Logic I and philosophy of language. On one use, the speaker has a particular person in mind and uses the description to help the listener identify that person. That is the referential use. On the other use, the speaker is not pointing to anyone specific, but is saying that whoever fits the description has some property. That is the attributive use.
This distinction matters because the surface grammar of a phrase does not always tell you how it is functioning in a sentence. Two sentences can look the same and still differ in what the speaker is doing with them. If someone says, “The winner of the race is wearing blue,” they might be referring to a person already in view, or they might simply be describing whoever ends up satisfying the description. The sentence form stays the same, but the pragmatic job of the phrase changes.
In a logic course, this is a reminder that natural language often carries more than simple truth conditions. A definite description is not just a label for an object, and it is not always best treated as a neat logical formula without context. Donnellan’s point pushes you to ask whether the description is being used to identify a target individual or to state a general condition about whoever fits it.
That difference also helps explain why people can disagree about a statement even when they both hear the same words. One person may hear the phrase as a reference to the wrong object, while another hears it as a description of the right kind of object. The mismatch is not just about vocabulary, it is about how language is being used in the conversation.
In Russell's style of analysis, definite descriptions are often treated as if they have a fixed logical structure involving existence and uniqueness. Donnellan does not simply reject that approach, but he shows that real language use is messier. A phrase can be logically analyzed one way and still be used in a more flexible, speaker-driven way in ordinary speech.
This distinction matters in Formal Logic I because it shows why translating English into symbols is not always mechanical. When you analyze a sentence with a definite description, you have to decide whether you are capturing the speaker’s reference or the descriptive content of the phrase. If you miss that, you can end up with a form that looks correct but does not match the actual argument.
It also connects directly to debates about whether meaning lives in the words themselves or in how a speaker uses them. Donnellan’s distinction is one of the clearest examples of how context changes interpretation without changing the sentence on the page. That is exactly the kind of thing you need to notice when a logic problem asks you to evaluate what a statement commits you to.
You will also see this when comparing theories of definite descriptions. Russell tries to analyze them in terms of existence and uniqueness, while Donnellan shows that some uses are more like pointing than describing. That makes this term a bridge between formal analysis and ordinary language, which is a major theme in the course.

A definite description is the phrase form Donnellan is talking about, usually something like “the F.” Donnellan’s distinction explains that the same definite description can function in more than one way depending on speaker intention and context. In logic problems, spotting the description is only the first step. You still have to ask how the phrase is being used in the sentence.
Russell's Theory
Russell's Theory gives a formal analysis of definite descriptions using existence and uniqueness. Donnellan’s distinction matters because it shows that real language use can be more flexible than Russell’s clean logical structure suggests. When you compare the two, you are really comparing a truth-conditional analysis with a use-based observation about reference.
referential use
Referential use is the side of the distinction where the speaker uses the description to get a particular individual in view. The phrase may succeed even if the description is not fully accurate, as long as the listener can tell who is being indicated. This is the use that often feels like pointing, even when no pointing gesture is present.
attributive use
Attributive use is when the speaker uses the description to say something about whoever fits it, not to name a specific person. This use is much closer to a general claim or property statement. In class examples, this is the reading you want when the point is about whoever satisfies the description, not about a known individual.
A quiz question or short-answer prompt will usually ask you to classify a definite description as referential or attributive, then explain why the context points that way. You might be given a sentence like “The man drinking a martini is a professor” and asked whether the speaker is identifying one person in the room or making a general claim about whoever fits the description.
In a problem set, the smart move is to look for clues in the surrounding context: Does the speaker seem to have a specific individual in mind? Would the statement still make sense if the description were false? Those clues tell you whether the phrase is doing referential work or attributive work. If your instructor uses Russell alongside Donnellan, be ready to explain why the sentence can be analyzed logically one way but used conversationally another way.
These are often confused because both deal with definite descriptions, but they do different jobs. Russell's Theory is a formal semantic analysis of the description itself, while Donnellan's distinction focuses on how a speaker uses that description in context. One is about logical form, the other is about use and reference.
Donnellan's Referential-Attributive Distinction separates two uses of the same definite description, not two different kinds of phrases.
Referential use points to a particular individual, even if the description is imperfect or partly wrong.
Attributive use describes whoever fits the phrase, so the statement is about the satisfier of the description rather than a known person.
In Formal Logic I, the distinction matters because context can change how you translate and analyze an English sentence.
This term is easiest to spot when a sentence looks simple on the surface but the speaker’s intention changes what the description is doing.
It is the idea that a definite description can be used referentially or attributively. Referential use points to a specific person the speaker has in mind, while attributive use talks about whoever fits the description. In Formal Logic I, that difference matters because it changes how you interpret and analyze the sentence.
Referential use is about identifying a particular individual, even if the description is not perfectly accurate. Attributive use is about anyone who satisfies the description. A good shortcut is that referential use feels like pointing, while attributive use feels like describing a category.
Look at the speaker’s intention and the surrounding context. If the description is being used to single out one specific person, it is referential. If the sentence is making a claim about whoever matches the description, it is attributive. The wording alone usually is not enough.
Russell gives a formal analysis of definite descriptions, but Donnellan shows that actual language use is more flexible than a purely logical reading. Some sentences are used to refer to a particular person, even when the descriptive content is not what really matters. That is why the distinction comes up in debates about meaning, reference, and context.
