- Accidental predication(as a way of making claims about temporary features)
- Saying something about a quality or property that isn't essential to what something is—like saying 'the dog is brown' describes something that could change without the dog ceasing to be a dog.
- Fârâbî(as a historical philosopher being referenced)
- A medieval Islamic philosopher (10th century) who wrote about logic and metaphysics; he's being discussed here because of his ideas about how language works.
- connective role(as a grammatical function)
- The function of connecting different parts of a sentence together, like how 'is' links a subject to a description.
- copula(Hobbesian logic)
- The word 'is' that links subject and predicate in a proposition, though not strictly necessary since word order could serve the same function
- essential predication(Distinguished from accidental and intentional predication by having quiddities as truth-makers.)
- Predication in which the predicate expresses a definitional or quidditative part of the subject's essence, independent of whether instances of the subject actually exist.
- estin(as a linguistic term)
- The Greek word for 'is' or 'to be'; in this context, it's the verb that connects a subject to what's being said about it (like the word 'is' in 'the sky is blue').
- linguistic anchor(as a language-based concept)
- A word or grammatical element in language that makes a distinction clear or real; without it, a difference would exist only in theory, not in actual language.
- semantic weight(as a linguistic concept)
- The amount of meaning a word carries on its own; a word with high semantic weight means something specific by itself, while one with low semantic weight mainly serves to connect other words.
