- Expression-sequences(what gets mapped between languages)
- Groups of words or sentences strung together in a language; basically, the actual strings of text you're trying to translate.
- Mapping(how Achinstein connects properties between the two subjects)
- In logic, this means connecting or matching one thing to another by showing how they correspond—like saying 'this property in swans works the same way as that property in line segments.'
- Quine(as a proper name referring to the philosopher whose theory is being discussed)
- Willard Van Orman Quine was a 20th-century American philosopher who wrote about how we know things and how language works. In this statement, we're discussing one of his specific ideas about observation.
- Reference (in philosophy of language)(what the translation manual must fix to make translation work)
- What a word or expression points to or stands for in the world—for example, the word 'dog' refers to actual dogs.
- Translation Manual(what's needed to fix a translation's meaning)
- A set of rules or guidelines that decides how to translate words and phrases from one language to another and what those words actually refer to.
- indeterminacy of translation(philosophy of language, opposed to Collingwood's re-enactment thesis)
- Quine's claim that it is not possible to achieve determinacy in translation
- proposition(Used in the context of a semantic theory sensitive to differences in subject matter.)
- The content expressed by a sentence, individuated at least in part by the subject matter of the sentence and the contents of its subsentential expressions.
