Lexical categories

The following is a basic list of grammatical terms. Most important are parts of speech, also known as word classes, or grammatical categories. The important words of sentence are called content words, because they carry the main meanings, and receive sentence stress Nouns, verbs, adverbs, and adjectives are content words. Minor words are called function words, which are less important in the sentence, and usually don’t get stressed. All other categories — such as prepositions, articles, quantifiers, particles, auxiliary verbs, be-verbs, etc. — are function words.


1 Content words

1.1 ADJECTIVE (adj.)

Modifies a noun. See also the adjectives page.

attributive We all live in a yellow submarine.
predicate Our submarine is yellow.


1.2 ADVERB (adv.)

Modifies verbs, adjectives, or other adverbs. We can distinguish various types, such as:

frequency: I often wear fruit on my head.
intensity: I love chocolate so much! I just can’t get enough!
manner The matter was dealt with graciously.
conjunctive: However, I don’t recommend that you try it.
sentence [sentential] adverb: I really don’t understand him.


=== NOUN (n.) Nouns can be classified according to mass (non-count) and count nouns, and according to proper/common nouns.


mass / substance / material I love drinking coffee.
count: I can’t imagine that eating a large pizza could make me gain so much weight.
common: I don’t trust politicians.
proper: I don’t trust Bob Dole or President Clinton.


Nouns can vary along various dimensions, like abstract (love, mercy) versus concrete (bottle, pencil). Some nouns are super-ordinate nouns that denote a general category, i.e., a hypernym, and nouns for members of the category are hyponyms.

  • equipment→ computer, scanner, microscope
  • furniture→ table, desk, chair, shelf


1.3 VERB (v.)

Verbs can be classified in many ways — according to properties (transitive / intransitive, activity (dynamic) / stative), verb form, and grammatical features (tense, aspect, voice, and mood). Most verbs are content words, while some (below) are function words.

Properties
transitive (trans.):

Can take an object.

I ate all the kiwis. I gave all the berries to the penguin.
intransitive (intrans.):

Can’t take an object.

All the kiwis disappeared.
activity (dynamic) I hiked the mountain and ran for an hour.
stative: The strawberries weigh over 2kg.
cognitive:

Stative verbs referring to mental states

I love berries.


Verb forms
basic form sneeze
infinitive: to sneeze
inflected form: She sneezes whenever she’s around cats.
gerund Sneezing is such an irritating thing.
participle The poor girl, sneezing from an allergy attack, had to rest.


Inflected forms
tense present I sneeze
simple past I sneezed
perfect I have sneezed
past perfect I had sneezed
voice active You are tricking me.
passive I was tricked.
aspect simple I sneeze
progressive I am seezing.
emphatic I do sneeze.
perfect / perfective I have sneezed.
habitual I sneeze (every day). I used to sneeze.
continuous I kept sneezing.
immediate future I’m about to sneeze. I’m going to sneeze.
mood (modality) indicative I am sneezing.
conditional I would / might / may sneeze.
imperative Don’t sneeze! Go see a doctor!
suggestive Let’s all sneeze together!

2.2 Pro-form

2.5 Determiners

A category that includes articles, possessive adjectives, and sometimes, quantifiers. Articles distinguish between mass versus count nouns, or between uses of a noun that are (1) more abstract, generic, or mass, versus (2) more concrete, delimited, or specified. See the page on determiners.

definite article the
indefinite articles a, an
demonstrative adj. this, that, these, those

2.8 Particle (par.)

A group of several miscellaneous kinds of minor function words.


complementizer Marks a that-complement clause. Complements without expressed subjects are often marked with that, and subjects of complement clauses are often marked with the particle for. I know that you took the money.

It would be crazy for them to go to Greenland for vacation.

discourse particle Express sentence pauses, or bridges between thoughts. Hmm...I just don’t know what to do.

Well, I think I’ll just go home.

phrasal verb particle [PVP] Combines with a main verb to make a phrasal verb. Look out!

2.9 Interjection (interj.)

  • Hey! Get out of my refrigerator!
  • Oh! Can you come here?
  • Ouch! That really hurt!
  • Rats! Darn it!


3 Sentence structure and position

We also classify words by their function or role in a sentence, and how they relate to other words and the whole sentence. A sentence with a linking verb can be divided into the subject (SUBJ) [or nominative] and verb phrase (VP), which contains a verb or smaller verb phrase, and a noun or adj. predicate (PRED). A noun or pronoun belongs to or makes up a noun phrase (NP), just as a verb belongs to or makes up a VP.

  • Penguins are birds.

[NP] [VP [NP]]

[SUBJ] [PRED]


In sentences with transitive verbs, the verb phrase consists of a verb plus an object (OBJ) — a direct object (DO), and possibly an indirect object (IO).

  • Penguins eat fish.

[SUBJ] [VP [DO] ].


I feedmy penguinsfish.

[SUBJ] [VP [IO] [DO] ].


The functions of nouns in a sentence, such as subject, object, DO, IO, and possessive are known as CASE.
