what is a grammar

A short dictionary-style entry defining grammar in plain English, with two small examples and a nearby distinction, plus an interactive hook with feedback.

A closer look

Grammar is the set of rules a language uses for changing word forms and putting words together into sentences.

It also means how well a person follows those rules. She goes works, she go does not; word order matters too.

Here is the agreement rule in one sentence: with he, she, or it in the present tense, most verbs take an -s. So He hates being in hospital is right, while He hate being in hospital is not. Other subjects, like we, keep the plain form: We often go to Edinburgh.

Grammar versus vocabulary

Grammar is different from vocabulary. Vocabulary is your stock of words, such as station, pick up, and late. Grammar is what turns that stock into a sentence, deciding the order and the endings.

The same three words show the difference. I picked her up late follows the rules; I her up late picked uses the same vocabulary but no longer works.

People sometimes say a learner has bad grammar when they simply lack words, or a rich vocabulary when the real gap is structure. Keep the two apart and it is easier to see which one needs work.

what is the grammar

Here's the short answer: when people talk about grammar, they usually mean the system of rules that decides how words change their form and combine into sentences in a language. This is how a learner's dictionary defines it: grammar is "the rules about how words change their form and combine with other words to make sentences." So grammar isn't a list of vocabulary or a set of tricky words to memorize. It's the underlying system that tells you things like: in English, you usually add *-s* to a verb when the subject is third-person singular (so you say *she walks*, not *she walk*), and that word order matters, so *the dog bit the man* means something quite different from *the man bit the dog*, even though the words are the same. A second, less common meaning: *grammar* can also refer to an actual book of grammar rules, as in "I bought a German grammar." That sense is marked as mainly British English. But in everyday speech, when someone says "your grammar is good" or "the grammar of this language," they're talking about the rule system itself, not a book. **Quick check:** In the sentence *She walks every day*, which part shows grammar at work? - good_result: The *-s* on *walks*. Right, that ending is grammar changing a word's form to show who is doing the action. - wrong_result: The word *every*. Not quite, that word adds meaning on its own; grammar is the system of rules for how words change form and combine, and it's the *-s* on *walks* that shows a rule in action. **Destination:** For a deeper look at how grammar differs from vocabulary, see the entry on "the difference between grammar and vocabulary."

what is present simple

The present simple is the English tense for habits, routines, general truths, and fixed situations. It is formed with the base form of the verb, adding -s for third person singular subjects like he, she, or it. For example, *I drink coffee every morning* and *She walks to work.* It differs from the present continuous, which describes actions happening right now: *She walks to work* is a habit, while *She is walking to work* means she is walking at this moment.

what are grammars

**A quick recognition test.** Ask what the grammar in question is *for*. If it describes or teaches a whole language, it is a grammar type. If it tells you about a single rule or points out one mistake, it is not. A reference grammar describing a language's major constructions counts, and a pedagogical grammar that sequences topics for learners counts too. A rule like *use fewer with count nouns* does not; that is one rule, not a whole grammar. **The main kinds you are most likely to meet.** - **Reference grammar.** Prose-like description of a language's major grammatical constructions, illustrated with examples. Its clue: you look things up in it, chapter by chapter, rather than reading it straight through to learn. - **Pedagogical grammar.** Built to teach someone the language, while also serving as a lookup tool. Its clue: the topics are sequenced for a learner, from easier to harder. - **Prescriptive grammar.** Tells speakers what they *should* do. Its clue: rules are stated as commands, like *avoid ending a sentence with a preposition*. - **Descriptive grammar.** Records how speakers actually speak and write, without judging. Its clue: it reports what happens rather than what should happen. - **Theoretical grammar.** the focus is on testing and building the theory, not on helping you use the language. **A boundary worth watching.** Pedagogical and reference grammars overlap in purpose, which makes them the easy pair to confuse. A pedagogical grammar can also be used for looking up details. The diagnostic is not where you use it but why it was written: teaching and sequencing come first in a pedagogical grammar, while a reference grammar is organized for lookup from the start. **Try it.** You find a book whose opening chapters introduce verb forms before passive sentences, with exercises at the end of each chapter. Which kind is it? good_result: Pedagogical grammar. The topics are sequenced for learners and there are exercises, which is the distinguishing clue. wrong_result: Reference grammar. Look at the organization: exercises and a teaching sequence point to a pedagogical grammar, not a reference tool arranged for lookup. To see the same test applied to real titles, browse the grammar descriptions in the reference section of your library catalogue.
