Parts of Speech: Articles and Determiners
A determiner is a word placed before a noun to show whether you mean something specific, general, owned, or counted. Articles (a, an, the) are the most familiar determiners, but they're just one type among several. This guide covers every category of determiner, the a/an rule and its exceptions, and the situations where no article is needed at all.
What Is a Verb?
A verb describes what the subject of a sentence is doing, experiencing, or being. It can show a physical action (run, eat, build), a mental action (think, believe, consider), or a state of being (be, seem, become).
Without a verb, a group of words is just a fragment, not a complete sentence. Even commands, which drop the subject, still need one: "Sit!" or "Listen!"
The Main Types of Verbs
Verbs fall into several overlapping categories. A single verb can belong to more than one type depending on how it's used.
Describe something physical or mental that happens directly in action.
Describe a state, feeling, or condition rather than an action. Generally not used in continuous tenses.
Work alongside a main verb to build complex tenses, moods, or form questions.
A specialized type of auxiliary verb expressing ability, possibility, permission, or obligation.
Connect the subject to a word that describes or renames it, rather than displaying an action.
Combine a verb with a preposition or adverb to create a brand-new meaning. Only the verb part is conjugated.
Transitive vs. Intransitive Verbs
This distinction decides whether a verb needs an object to complete its meaning, and it's one of the most common sources of confusion.
- Transitive verbs act on a direct object, the thing or person receiving the action ("She read the book"). Without an object, the sentence feels incomplete ("She read" raises the question, read what?).
- Intransitive verbs are complete without an object ("They laughed"). No object is needed, and adding one wouldn't make sense.
- Ditransitive verbs take both a direct and an indirect object ("She gave him the book"). Here, book is the direct object (what was given) and him is the indirect object (who received it).
- Ambitransitive verbs can work either way depending on the sentence: "I already ate" (intransitive) vs. "I already ate a sandwich" (transitive).
| Type | Needs an Object? | Example |
|---|---|---|
| Transitive | Yes, a direct object | She baked a cake. |
| Intransitive | No | The baby slept. |
| Ditransitive | Yes, direct and indirect | She baked him a cake. |
Regular vs. Irregular Verbs
Regular verbs form the simple past and past participle by adding -ed to the root: walk → walked. Irregular verbs don't follow this pattern, and their past forms have to be memorized individually.
| Base Form | Simple Past | Past Participle |
|---|---|---|
| be | was / were | been |
| go | went | gone |
| have | had | had |
| do | did | done |
| see | saw | seen |
| take | took | taken |
| make | made | made |
| get | got | gotten / got |
| know | knew | known |
| think | thought | thought |
| come | came | come |
| give | gave | given |
| find | found | found |
| write | wrote | written |
| speak | spoke | spoken |
Gerunds & Infinitives
Both gerunds and infinitives turn a verb into a noun, but they aren't always interchangeable. A gerund adds -ing to the verb ("Swimming is fun"). An infinitive adds to before the root form ("To swim is fun").
| Use | Form | Example |
|---|---|---|
| Object of a preposition | Gerund only | "I'm interested in learning." |
| After verbs like want, decide, hope | Infinitive only | "I want to leave." |
| After verbs like enjoy, avoid, finish | Gerund only | "I enjoy reading." |
| General or abstract statements | Infinitive | "To exercise is important." |
| Specific or completed actions | Gerund | "I liked exercising this morning." |
Verb Tenses: A Quick Map
English uses 12 main tenses, built from four structures (simple, continuous, perfect, perfect continuous) across three time periods (past, present, future).
| Period | Simple | Continuous | Perfect | Perfect Continuous |
|---|---|---|---|---|
| Present | I walk | I am walking | I have walked | I have been walking |
| Past | I walked | I was walking | I had walked | I had been walking |
| Future | I will walk | I will be walking | I will have walked | I will have been walking |

Active vs. Passive Voice
In the active voice, the subject performs the action: "The chef cooked the meal." In the passive voice, the subject receives the action instead, formed with a conjugated form of be plus the past participle: "The meal was cooked by the chef."
Active voice is generally clearer and more direct, which is why most style guides recommend it for everyday writing. Passive voice is useful when the doer of the action is unknown or unimportant: "The window was broken."
Subject-Verb Agreement
A verb has to match its subject in number. Singular subjects take singular verbs; plural subjects take plural verbs.
- "The dog barks." (Singular)
- "The dogs bark." (Plural)
This gets trickier with collective nouns and compound subjects, where the correct verb form isn't always obvious at first glance.
How to Identify a Verb?
If you're unsure whether a word is a verb, try these two quick tests:
- Can you do it? Ask, "Can I ___?" Can I think, walk, exist? If yes, it's likely a verb.
- What is happening? In "Mark eats his dinner quickly," what's happening? Eating. That's the verb.
Is ___ a Verb? Quick Answers
Some of the most common words in English shift roles depending on the sentence.
| Word | Answer |
|---|---|
| to | Usually a preposition or the marker before an infinitive ("to run"), not a verb on its own. |
| being | Can be a verb form ("She is being kind") or a noun/gerund ("Being on time matters"). |
| have | A main verb showing possession ("I have a car") or an auxiliary verb building tense ("I have finished"). |
| well | Almost never a verb. Usually an adverb ("sings well") or adjective ("feeling well"). |
| like | Can be a verb ("I like coffee"), preposition ("like the wind"), or conjunction ("like I said"). |

Frequently Asked Questions
What is a determiner?
A determiner is a word placed before a noun to show whether it's specific, general, owned, or counted, such as a, the, this, or my.
Are articles and determiners the same thing?
Not quite. Articles (a, an, the) are one type of determiner, but determiners also include demonstratives, possessives, quantifiers, and more.
What is the rule for using "a" vs. "an"?
Use a before a consonant sound and an before a vowel sound. This is based on pronunciation, not spelling, which is why it's "a university" but "an hour."
What are the main types of determiners?
The main types are articles, demonstratives, possessive determiners, quantifiers, distributives, determiners of difference, and predeterminers.
What is the difference between "a few" and "few"?
"A few" suggests a small but sufficient amount ("a few books" means some, probably enough). "Few" suggests an insufficient amount ("few books" means not enough).
When do you skip the article entirely?
Articles are usually skipped with languages, sports, academic subjects, meals, and generic plural or uncountable nouns, such as "She plays tennis" or "We like music."
What is a predeterminer?
A predeterminer comes before another determiner, usually to add emphasis or express degree, such as such in "such a mess" or quite in "quite a surprise."
Is "the" always required with proper nouns?
No. Most proper nouns skip the article, but exceptions include geographic features, pluralized names, and institutions, like "the Sahara" or "the Netherlands."
Can the same word be a determiner and a pronoun?
Yes. Words like this, that, some, and many function as determiners before a noun, but as pronouns when they stand in for a noun on their own.
Why are articles hard for some English learners?
Some languages don't use articles at all, or use a completely different system for marking definiteness, which makes English article rules something that often takes longer to master than other grammar points.
Can Learna help me stop missing articles like "a" or "the"?
Yes. Learna catches missing, extra, or mismatched articles as you speak and explains the specific rule behind each correction.
Does Learna adjust its feedback based on my native language?
Yes. Learna adapts corrections based on the patterns learners from different language backgrounds commonly run into, including with article use.
