Nouns are words that represent people, places, things, or ideas.
Adjectives modify nouns by describing their qualities or characteristics.
Adverbs modify verbs, adjectives, or other adverbs to indicate how an action is performed or the degree to which it occurs.
The nominative case in a grammar marks the subject of a verb.
A sentence must have both a subject and a verb to be complete.
The object is what receives the action performed by the subject.
Prepositions indicate relationships between words.
Pronouns take the place of nouns to avoid repetition.
Introduction to words
1. Lexical words, function words, and inserts
2. The structure of words: morphology
3. Multi-word units: idioms, collocations, and lexical bundles
Lexical word classes
The structure and function of lexical words: nouns, verbs, adjectives, and adverbs
Comparing lexical word classes in use
Borderline cases in classifying words
Function word classes
The structure and function of function words: determiners, pronouns, auxiliary verbs, prepositions, adverbial particles, coordinators, and subordinators
Special classes of words
In grammar, we first need to identify the types of grammatical units, such as words and phrases, before describing the internal structure of these units, and how they combine to form larger units
Grammatical units are meaningful elements which combine with each other in a structural pattern
Grammar is the system which organizes and controls form-meaning relationships
Types of grammatical units
Sentence
Clauses
Phrases
Words
Morphemes
Morphemes are parts of words, i.e. stems, prefixes, and suffixes
Morphology
The part of grammar dealing with morphemes
Syntax
The part of grammar dealing with words, phrases, clauses, and sentences
Grammatical units can be combined to form longer written texts or spoken interaction, known as discourse
Language can be analyzed in terms of its phonemes and graphemes, the smallest units of speech and writing
Sentences are primarily of interest in the study of written language
Grammatical units are described in terms of their structure, syntactic role, meaning, and the way they are used in discourse
Units can be described in terms of their internal structure: e.g words in terms of bases and affixes, phrases in terms of heads and modifiers, and clauses in terms of clause elements
Units can be described in terms of their syntactic role
Units can be described in terms of meaning
Units can be further described in terms of how they behave in discourse
Pronouns like it and they are often used to refer back to things mentioned earlier in the same discourse
Such pronouns are more common in speech than in written texts
Words are generally considered to be the basic elements of language
Words are relatively fixed in their internal form, but they are independent in their role in larger units
Insertions between words
Insertions can usually be made between words but not within words
Orthographic words are the words that we are familiar with in written language, where they are separated by spaces
Grammatical words fall into one grammatical word class (or 'part of speech') or another
Lexemes are a set of grammatical words which share the same basic meaning, similar forms, and the same word class
Each occurrence of a word in a written or spoken text is a separate token
In contrast to word tokens, word types are the different vocabulary items that occur in a text
Words can be grouped into three families: lexical words, function words, and inserts
Lexical words
Nouns
Lexical verbs
Adjectives
Adverbs
Lexical words are the main carriers of information in a text or speech act
Lexical words are the most numerous and their number is growing all the time
