Understanding language, its structure, and meaning
- Classical definition
- The science of speaking correctly and the interpretation of the poets. (Quintilian, Institutio Oratoria I.4.2.)
- Proper object
- Language as the sign of thought, learned in the texts that use it well.
- Place in the order

Grammar is the art of reading language exactly: what each word is, what each phrase is doing, and what a sentence does and does not claim. It comes first because every later art, from a proof to a measurement report, is written in sentences that can be read well or badly. A contract clause, an error message and a news headline all reward the same habit of parsing before judging.
The guiding questionWhat exactly does this say, and what does it leave unsaid?
Round 1 opens soon
The spiral
Three strands, three rounds
Each strand comes back in every round, a level deeper. Finish Round 1 across the arts before Round 2: breadth first, then depth.
Round I Foundations
- Parts and structureName the parts of speech and parse a sentenceI can label every word in a plain sentence of 15 to 25 words by its part of speech, and say what job each phrase does.
- Definition and meaningDefine a term by genus and differenceI can write a definition of an ordinary term that names its kind and what sets it apart, and test it against examples and counterexamples.
- Close readingRestate a passage and find its ambiguityI can restate a short passage in my own words, separating what it states from what I infer, and mark one ambiguous word or phrase.
Round II Practice
- Parts and structureParse complex sentences and repair themI can parse a sentence with subordinate clauses, find the head of each phrase, and rewrite it so that it is clear who does what.
- Definition and meaningChoose the right kind of definitionI can say whether a definition is stipulative, lexical or operational, and rewrite a vague term as a definition with a measurement and a threshold.
- Close readingRead scope, negation and quantifiersI can read the scope of 'all', 'some', 'not' and 'only' in ordinary claims and show how moving one changes what is claimed.
Round III Mastery
- Parts and structureAnalyse a hard sentence from a primary textI can diagram a long sentence from a primary text, state its claim, its qualifications and its connectives, and say what would change if one connective were swapped.
- Definition and meaningSettle a verbal dispute and trace a change of meaningI can show whether a stubborn disagreement is verbal or real by fixing its key term, and trace how a word's meaning changed without arguing from its roots.
- Close readingRead signs, sense and referenceI can explain the difference between what a term means (its sense) and what it picks out (its reference), and between a sign and what it signifies, and use the difference to take apart a misleading claim.

Grammar · Round 1
- Augustine of Hippo, Confessions, I.8.13 (Book I, chapter 8, section 13)J. G. Pilkington's translation (Nicene and Post-Nicene Fathers, First Series, vol. 1, 1887), public domain, as revised for New Advent. Read the whole of section 13, where Augustine describes how he learned to speak.
- Dionysius Thrax (attributed), The Art of Grammar, sections 12 to 25 in Davidson's numbering (12 the word, 13 the sentence and the list of eight parts, 14 noun, 15 verb, 19 participle, 20 article, 21 pronoun, 23 preposition, 24 adverb, 25 conjunction)Thomas Davidson's 1874 translation, 'The Grammar of Dionysios Thrax' (Journal of Speculative Philosophy 8, pp. 326-339), public domain. Davidson thought the work genuine, but its authorship is now disputed: Vincenzo Di Benedetto argued in 1958 that only the opening sections go back to Dionysius (2nd century BC) and that the rest, including the parts of speech, was compiled in the 3rd or 4th century AD. Many specialists agree, though some still defend the attribution. Read it as the short school grammar that shaped later Greek and Latin teaching, not as the certain work of one author. Other editions number the sections differently.
Augustine says he learned to speak by watching which things his elders named and moved towards, and by reading their faces, glances and tones. Dionysius sorts the words of a sentence into eight kinds. What does each account assume a word is, and which of the two explains better how a child first learns what a word means?
- Augustine says he gradually gathered what things words were the signs of. Are all eight of Dionysius's parts signs of things, or do some, such as the article and the conjunction, do a different job?
- Dionysius defines a noun as a declinable part of speech signifying something concrete or abstract (section 14). Is 'nobody' a noun by that test, and what does the test miss?
- Augustine's account suggests that a child learns 'this' by pointing. What is left to learn after the pointing, and who must already know what?
Grammar · Round 2
- Plato, Cratylus, 383a-391bH. N. Fowler's Loeb translation with the Greek, on Perseus. Hermogenes reports Cratylus's view and gives his own at 383a-384e; Socrates asks whether names can be true or false at 385b-d and calls a name an instrument of teaching and of separating reality at 388b-c; the user of the instrument is the dialectician at 390c-d. The etymologies that follow are outside this span.
Hermogenes says a name is whatever anyone decides to call a thing, and Cratylus says each thing has a name that belongs to it by nature. Socrates replies that a name is a tool for teaching and for sorting things out, like a shuttle in weaving. If a name is a tool, what makes it a good one, and who is entitled to judge?
- At 385a Socrates asks what happens if a private person calls what we call a horse a 'man'. What would it cost Hermogenes to say that the name is then right for that speaker?
- Socrates says the user of a tool, not its maker, is the judge of whether it is well made (390b-d). Who is the user of a word today: the speaker, the listener or the dictionary writer?
- If names are conventions, can a convention still be better or worse? Use an example from a technical vocabulary you know.
Grammar · Round 3
- John Locke, An Essay Concerning Human Understanding, Book III, chapter 2 (Of the Signification of Words), sections 1 to 5, and chapter 9 (Of the Imperfection of Words), sections 4 to 6Project Gutenberg's edition of Books III and IV (volume 2), public domain, which it describes as based on the second edition. Locke goes on to propose remedies in chapter 11, which is optional here.
Locke says that words, in their primary signification, stand for nothing but the ideas in the mind of the person who uses them, yet we all suppose our words also stand for the ideas in other people's minds and for the things themselves (III.2.2, 4, 5). If that is so, what exactly is shared when two people understand one another, and what does Locke think can go wrong?
- Locke says the doubtfulness of words has its cause more in the ideas they stand for than in the sounds (III.9.4), and that it is worst for the names of complex ideas such as moral words and for the names of substances (III.9.5-6). Test this on two words of your own choosing, one you can point to and one you cannot.
- If every word had one exact definition agreed by all, would we have a perfect language? What would be lost?
- Locke treats words as signs of ideas. How would a speaker who held that words stand directly for things answer him?
