# How Do We Break Down English Grammar? “The list divides all animals into 14 categories: Those that belong to the emperor Embalmed ones Those that are trained Suckling pigs Mermaids (or Sirens) Fabulous ones Stray dogs Those that are included in this classification Those that tremble as if they were mad Innumerable ones Those drawn with a very fine camel hair brush Et cetera Those that have just broken the flower vase Those that, at a distance, resemble flies” - Jorge Luis Borges When you are trying to categorize something, sometimes you don't know what you'll end up with. OK, we have tests for users to take, but how do the users figure out what test to take? Oh, we have tags for this. I produced them quite a long time ago so that we could build UI around them. But do our tags actually help the end users? Do they really do the job? I was thinking like this when it became clear that they likely don't. Were never designed to. What the tags hierarchy looked like? Well, I believe, I'll do the reader a favor by not presenting it here at all. It all started with the strange idea that it is possible to somehow use EAQUALS descriptors to index tests. ## EAQUALS Descriptors Initially, I was intending to base our taxonomy on CEFR levels. This is the road that led me to EAQUALS descriptors. A terrific idea? Rather terrible, as I soon understood. The problem is that the descriptors were never intended to serve as an index for anything. Their purpose is to help with figuring out levels of language mastery instead. This is why their goal is not to describe grammar as a whole, and they may contain duplicates at different CEFR levels, and so on. Anyway here are they, as they are outlined [here](https://englishagenda.britishcouncil.org/sites/default/files/attachments/pub-british-council-eaquals-core-inventoryv2.pdf). Use the mind map to see for yourself. You can pan, zoom in and out the map and collapse and expand the nodes. ![EAQUALS Descriptors](mindmap://article/tags/eaquals)

Even though I abandoned the idea of using EAQUALS descriptors as tags, we still decided to keep CEFR levels as an independent tags hierarchy. So, we still need a taxonomy. Where do I begin? That's easy! I'll adopt a sound contemporary grammar. Cambridge Grammar of English Language is a great candidate, isn't it? ## Cambridge Grammar of English Language, The I start reading and soon begin to appreciate how straight the book describes English syntax. The grammar does not prescribe how one should use English but describes how English is used. Sentences are viewed as built from constituents. Clauses are built up from phrases; phrases are comprised of their respective heads and dependents. Different constituents might bear certain grammatical functions under defined circumstances. Places where phrases may occur in sentences depend on the types of their heads. You can't encounter an 'exception from a grammar rule' there, and there is no Future Perfect Continuous. What you can find are remarks like “we depart from the tradition of English grammar at many points, sometimes quite sharply. For example, in this book, the reader will find nothing of 'noun clauses', 'adjective clauses', or 'adverb clauses' because that traditional distinction in subordinate clause classification does not divide things satisfactorily and we have abandoned it.” More examples? Determinatives aren't adjectives, pronouns are nouns, nouns in prepositional phrases are complements to prepositions and 'will' is a modal like 'can'. You can refer to the mind map to get the idea. Please note, that I'm neither a linguist nor have really rigorously checked the map. It also has some categories more expanded than others to make a point, e.g. 'verb phrase' node. Nethertheless, if you see that I got something wrong, please, do give me a tip in comment. ![CGEL Mind Map](mindmap://article/tags/cgel)

A great grammar, isn't it? Should we base our taxonomy on it? Well, I have a crouching suspicion that it might not be easy to perceive or comprehend. Sure, it might be the number one choice for an individual of a highly intelligent alien species, but it still might be a little bit too much for even an advanced English learner. There are also other grammars, good and comprehensive. Gosh, this is depressing! On the other hand, being a non-native speaker, I supposedly have the advantage of being able to say what is not easy to understand. The challenge is thus to obtain a compelling taxonomy. Having one, I will know that it's not too bad. The quest continues. Why not to try grammar reference books' contents pages? Sounds like a reasonable idea. ## English Grammar in Use by Raymond Murphy The breakdown is based on my faulty interpretation of the contents page of “English Grammar in Use” by Raymond Murphy. ![Raymond Murphy English Grammar in Use Mind Map](mindmap://article/tags/murphy)

As we see, the contents appear to be organized to fulfill the needs of some specific group of learners interested in particular constructs. Usage examples with or instead of grammar categories look very practical: they make it easier for the reader to find his way around. It's a pity that such “category names” end up being too long to serve as tags. Apparently, it's important that the classification is designed to serve as a contents section of a book. Perhaps, if the author intended it for hypertext, it would differ. Another consequence is that the structure reflects the content of different modules of the book, as contrasted with the grammar of the language. Looks like another miss. What else? Why not figure out how other people with similar task at hand approach it? ## British Council, Supposedly In the dark depths of my work notes, there was a list. I assume that I somehow produced it using a British Council website, my notes didn't tell me which exactly. I was successful in finding some of the constructions in Google cache but failed to find the source of the whole taxonomy. It might have never existed as a whole. I might have produced it myself based on a menu structure or header or in a like manner. I can't remember, sorry. Still I think it's interesting and worth being mentioned here. ![Another Mind Map](mindmap://article/tags/bc)

### Grammar - Adjectives - adjective order - adjectives - as ... as - comparatives superlatives - like, as - much, far, a little, lots + comparatives - participle adjectives - Adverbials - adverbial phrases - adverb position in sentence - adverbs - comparative & superlative adverbs - enough, too, too much - no, not - so, such - still, yet, already - very, too - Connected discourses - clauses - cohesion - discourse - exclamations - linking words - addition - linking words - cause and effect - linking words - contrast - linking words - sequence - paragraph organisation - participle clauses - reference - relative clauses (who, which, that, whose) - signposting words & phrases - substitution & ellipsis - text organisation - topic sentences - word order in sentences - Determiners - articles (a, an, the, zero) - demonstratives (this, those) - determiners - much, many, a lot, little, few - some, any, no, someone, anything - punctuation - Prepositions - ing after prepositions - phrasal verbs (prepositions, particles) - prepositional phrases (place, time) - prepositional phrases (time, movement) - prepositions - Pronouns & Nouns - all, everybody, everything - countable & uncountable - impersonal pronouns (one, you, they) - indefinite pronouns - ing as subject, object - noun phrases - one(s) (big green ones) - personal pronouns (I, me) - plurals - possessives (my, mine) - possessives (of, 's) - pronouns & nouns - pronouns - questions - pronouns - this, that, these, those - proper nouns - reciprocal pronouns - reflexive pronouns (myself) - relative pronouns - use of 'it' - whoever, no matter who - Verb - Auxiliary Verbs - do (auxiliary) - negatives - Conditionals / Hypotheticals - if sentences - if sentences: past meaning - if sentences: present & future meaning - if, unless, in case - it's time, would rather - wish, if only - Main Verbs - be - delexical verbs - get structures - have - have (as main verb) - have, have got (possession) - imperatives - infinitive of purpose - infinitives (simple, perfect, ...) - infinitives (with, without 'to') - irregular verbs - link verbs - stative verbs - there is, are - verb patterns - verbs with two objects - Modal Auxiliary Verbs - can - could - had better - may, might - must, have to - need - ought to - shall - should - supposed to - will - will or shall - would - Questions - inversion - negative questions - question tags - question words - short answers - which, what (what size?) - Tenses Aspects Moods - future in the past - future perfect - future perfect progressive - future progressive - futures with if & when - going to - have something done - indirect speech - infinitive or ing? - passive - past perfect - past perfect progressive - past progressive - past simple - perfect aspect - present perfect progressive - present perfect simple - present progressive - present progressive (for future) - present simple - present simple (for future) - progressive aspect - since, for - used to (past)

This is another classification that helps the reader to find what he or she is after. This might be close to what we need... Actually, for the first time, I have a disturbing feeling that it might be better than whatever we end up with. Please pardon me for being opinionated, but I would argue that it's not ideal for us. Why? Firstly, it contains too many topics, it's too detailed. Secondly, you will laugh, but it appears to be... not enough theoretical and fundamental to me. You cannot just read CGEL without repercussions, I guess. Let's try something they use to harass natives in school this time. ## English Grammar and Composition by John E. Warriner ![English Grammar and Composition by John E. Warriner Mind Map](mindmap://article/tags/warriner)

Looks reasonable, even a bit basic. I couldn't get my hands on the actual book this time. Maybe this is why the index is not detailed enough. I'm intending to do it later. For now, it isn't going to serve as a good tags tree for us. Let's refer to Wikipedia! ## Wikipedia ![Wikipedia English Grammar Mind Map](mindmap://article/tags/wikipedia)

### Grammar - **Word classes and phrases** - Nouns - Phrases - Gender - Determiners - Common determiners - Articles - Definite - Indefinite - Quantifiers - Words that enumerate / indicate alternatives - Personal determiners - Other cases - Zero determiner - Combinations of determiners - Determiners and adjectives - Pronouns - Personal - Demonstrative and interrogative - Relative - "There" - Other - Verbs - Inflected forms - Principal parts - Base form - Third person singular present - Past tense - Past participle - Present participle - Copular, auxiliary and defective verbs - Archaic forms - Syntactic constructions - Tenses, aspects and moods - Simple and progressive - Perfect - Future and conditional - Passive voice - Imperatives - Questions, negation, inversion and emphasis - Use of verb forms - Finite forms - Non-finite forms - Objects and complements - Phrasal verbs - Phrases - Adjectives - Comparison - Phrases - Adverbs - Phrases - Prepositions - Conjunctions - Case - Declension - Number - Possessives - **Clause and sentence structure** - Word order - Questions - Dependent clauses - Negation - Imperatives - Elliptical constructions

What can I say here? It's surprisingly good. I think we could probably go with something like this. My arguments against are: - It's too academic when it comes to terms' names, and the names are too long; - Yet it's rather casual when considered as an index for a grammar; - It has different levels of detail for different topics (which might be my fault); - There are too many terms. As I don't seem to be able to adopt even a reasonably good taxonomy, the only remaining choice is to roll my own. ## Our version The main goal was to help our users find their way around our content. ~~Cooking up~~ composing our own hierarchy, I followed the principles listed below. 1. Terms should follow ESL/EFL tradition as opposed to scientific tradition. 2. Terms should be easily recognizable by non-professionals. - Popularity is more important than precision. - Familiarity is more important than correctness. 3. The taxonomy should be built from general to specific. 4. It should be comprehensive enough. 5. Good, if the terms are granular and orthogonal where applicable. 6. Smaller is better than larger. I decided to not recognize syntax as a separate term. It's too academic. After all, who in the world searches for "syntax"? Another discovery was that clear separation of concerns, with parts of speech, clause constituents and grammar functions, leads to CGELish taxonomy in no time. With a heavy heart, I dropped that idea too. Some tags were joined together to fit categorizing test questions e.g., "Countable and uncountable". A number of other lucrative shortcuts were taken. So, here it is. ![Our Grammar Tags Mind Map](mindmap://article/tags/tags-map)

See as list...

### Grammar - **Parts of speech** - Noun and pronoun - Noun - Pronoun - Countable and uncountable - Number - Case - Possessive - Person - Verb - Tense - Present - Historical - Past - Future - Simple - Continuous / Progressive - Perfect - Habitual - Mood - Indicative - Imperative - Subjunctive - Auxiliary - Modal - Be - Finite - Infinitive - Irregular - Gerund - Passive - Participle - Phrasal - Transitive and intransitive - Adjective and adverb - Adjective - Adverb - Comparative and superlative - Determinative - Article - Demonstrative - Preposition - Conjunction - Interjection - Particle - **Sentence and structures** - Clause and sentence - Sentence - Complex - Compound - Clause - Relative - Declarative - Interrogative - Question - Exclamative - Imperative - Independent - Dependent - Conditional - Phrase - Negation - Word order - Inversion - Function - Subject - Predicate - Complement - Object - Modifier - Intensifier - Determiner - Quantifier - Coordination - Supplementation - Argument - Indirect speech - Adjunct - Deixis and anaphora - **Morphology** - Word - Lexeme - **Punctuation** - Apostrophe - Colon - Comma - Dash and hyphen - Elipsis - Exclamation mark - Period - Question mark - Quotation mark - Semicolon

The terms are intended to be used as tags which can be combined e.g. if **Noun** and **Phrase** tags are used together, this might indicate **Noun** + **Phrase** = Noun phrase, or, say, **Verb** + **Present** + **Perfect** + **Passive** = Verb in present perfect tense and passive voice. > We will update this article to keep up with current understanding of what grammar taxonomy best fits our scenario. > If you notice any error, please leave a comment below.
