THE MASTERY CLUB · LEXICAL CATEGORIES · WORD → CLASS → GRAMMAR → MEANING → POSITION → MORPHOLOGY → USE
Lexical categories, also called word classes or parts of speech, organise English vocabulary by how words behave in sentences. The four major open lexical classes are nouns, verbs, adjectives and adverbs, while English also contains prepositions, pronouns, determiners, conjunctions, auxiliaries, numerals, interjections and other more closed or grammatical classes. A learner who knows a word’s dictionary meaning but not its word class can still misuse it: analyse, analysis, analytical and analytically share a family but do different grammatical jobs.
For learners searching for parts of speech, word classes, nouns verbs adjectives adverbs, lexical categories, open class and closed class words, word class examples, noun verb adjective adverb word families, or ways to improve sentence-level vocabulary, the key idea is distribution. A word class is not defined only by meaning. Nouns often refer to entities, verbs often express actions or states, adjectives often describe properties and adverbs often modify verbs, adjectives or larger clauses—but reliable classification also depends on where the word can appear, what inflections it takes and what constructions it enters.

The 60-Second Answer
A part of speech is a grammatical group into which words are classified according to their use. Cambridge Grammar identifies nouns, verbs, adjectives and adverbs as the four major word classes. These classes contain many thousands of members and readily admit new words, which is why they are often called open classes. Other classes such as pronouns, determiners, conjunctions and many prepositions are smaller and more grammatically constrained.
Word-class knowledge is practical vocabulary knowledge. If a sentence needs a noun after an article, decision may fit where decide does not. If a linking verb needs an adjective, effective may fit where effectively does not. If a verb requires an adverbial modifier, carefully may fit where careful does not. Vocabulary becomes usable when meaning and grammatical category are retrieved together.
What a Word Class Is
A word class groups words that share important grammatical behaviour. For vocabulary learners, classification matters because sentence grammar places constraints on which lexical form can occupy a slot. Meaning may suggest a family, but word class determines which family member can actually enter the construction.
A practical identification routine uses three kinds of evidence. First, inspect morphology: plural -s, verbal tense, adjective suffixes or adverbial -ly can provide clues. Second, inspect distribution: what comes before and after the word? Third, test substitution with a known member of the suspected class.
Do not rely on simplistic semantic definitions alone. Nouns can name processes and ideas, verbs can express states rather than actions, adjectives can classify rather than describe, and adverbs can modify entire clauses. Distribution and grammar are more reliable when intuition becomes uncertain.
For production, start from the sentence frame and ask what category is required. Then retrieve the correct member of the word family and check collocation. This turns parts-of-speech knowledge into vocabulary control rather than grammar terminology.
Parts of Speech
Part of speech is a traditional label for grammatical categories such as noun, verb, adjective and adverb.

Identification task: mark the surrounding words that reveal the grammatical role. Then replace the target with a known member of the same class. If the sentence structure remains grammatical, the distributional evidence supports the analysis.
Vocabulary task: compare whether meaning changes with category. Some class shifts preserve a close semantic relationship; others represent distinct senses or homonyms. Store each high-value use with its own sentence frame rather than assuming the spelling determines one lexical entry.
82. legal
Classes: adjective / noun in informal shorthand. Examples: legal advice; legal as department shorthand. Register affects category acceptability.

Lexical Categories and Word Classes FAQ
What is a part of speech?
A grammatical category into which words are classified according to their use, such as noun, verb or adjective.
What is a word class?
Another term for a grammatical category of words with shared distribution and behaviour.
What are the four major word classes in English?
Nouns, verbs, adjectives and adverbs.
What are open-class words?
Word classes that readily accept new members, especially nouns, verbs, adjectives and many adverbs.
What are closed-class words?
Smaller grammatical classes such as pronouns and determiners that change more slowly.
What is a noun?
A major word class that heads noun phrases and often refers to entities, concepts, processes or states.
What is a verb?
A major word class that heads verb phrases and expresses events, states, processes or relations.
What is an adjective?
A major word class that modifies nouns or functions in predicative constructions.
What is an adverb?
A diverse class that modifies verbs, adjectives, clauses or discourse.
What is a preposition?
A word class that heads prepositional phrases and expresses relations.
What is a pronoun?
A closed-class form that can occupy noun-phrase-like positions and encode reference.
What is a determiner?
A word class that structures noun phrases through definiteness, quantity, deixis or possession.
What is a conjunction?
A word that links clauses, phrases or other grammatical units.
What is an auxiliary verb?
A grammatical verb contributing tense, aspect, voice, modality or clause structure.
Why is meaning not enough to identify word class?
Abstract nouns, stative verbs and multi-class words show that semantic definitions are too simple.
How can I identify a word class?
Use distribution, morphology, sentence position and substitution with known members of the class.
Can one word belong to two parts of speech?
Yes. English has many multi-class forms such as book, fast, round and light.
What is conversion?
A category change without an overt derivational affix, such as noun email becoming verb email.
Why do suffixes help identify word class?
Many derivational suffixes are associated with nouns, verbs, adjectives or adverbs.
Are suffixes perfect predictors?
No. Exceptions and homographic endings mean sentence evidence is still necessary.
How do word classes help vocabulary?
They tell learners which family member fits a grammatical slot and how the word behaves in phrases.
How do word classes help reading?
Category expectations help readers predict sentence structure and infer unfamiliar forms.
How do word classes help writing?
Writers can choose the noun, verb, adjective or adverb form required by grammar.
How do word classes help speaking?
Fast lexical retrieval includes choosing the grammatically correct category.
How do dictionaries show word class?
Entries label noun, verb, adjective, adverb and other categories by sense.
How do corpora show word class?
Part-of-speech tagging allows searches and frequency counts by grammatical category.
What is the difference between word class and word family?
A word family links morphologically related forms; those forms can belong to different grammatical categories.
What is the difference between content and function words?
Content words carry substantial lexical meaning; function words mainly organise grammatical relations.
Are all nouns people, places or things?
No. Nouns also name abstract concepts, events, processes, qualities and relations.
Are all verbs actions?
No. Verbs can express states, possession, cognition and relations.
Do all adverbs end in -ly?
No. Fast, hard, late and many other adverbs have no -ly ending.
Do all -ly words function as adverbs?
No. Friendly, lovely and likely can function adjectivally.

Evidence Note
Cambridge Dictionary defines a part of speech, also called a word class, as one of the grammatical groups into which words are divided according to use. Cambridge Grammar identifies nouns, verbs, adjectives and adverbs as the four major word classes and notes that many English forms belong to more than one class. Modern syntax also treats distribution—the positions and constructions in which words can occur—as central evidence because purely semantic definitions such as “a noun names a thing” or “a verb names an action” are too weak for many real examples.
