how + to-infinitive

Common collocations

Grammar Patterns

how + do/does/did + subject + verb

how + modal + subject + verb

Common Mistakes

Can you show me how I can make sushi?' (correct but wordy)
Can you show me how to make sushi?
Use the shorter how + to-infinitive pattern when the subject is the same.
I don't know how does this work.
I don't know how this works.
In embedded questions, keep subject-verb order.

Example

how + be + subject + after [event]

I called the clinic to ask how the patient was feeling this morning.

how + subject + be + feeling

Common collocations
  • how is

  • how is someone doing
Synonyms
  • in what state

    more formal; used in written medical or formal contexts

Grammar Patterns

how + be + subject

how + be + subject + feeling/doing

Usage Note

Unlike sense 6 (WELL-BEING), this sense asks about a specific condition after a particular event — an illness, exam, move, or other change — and expects a detailed answer rather than a short social reply.

Common Mistakes

How is your father does after the operation?
How is your father after the operation?
Do not add do/does when be is the main verb.

3. used to ask for an evaluation of an event, activity, or experience that has happ

3.adverbA1

Example

How did Yael's first cooking class at the community centre go?

how + did + subject + go

Common collocations
  • how was
  • how did it go
  • how was your day
  • how was the trip
Synonyms

Grammar Patterns

how + be + subject

how + did + subject + verb

Usage Note

Very common after events that have just finished. The verb is usually be, go, or turn out. Expects an evaluative answer (good/bad/fun/boring).

Common Mistakes

How was your weekend?' 'I was fine.' (mixing up experience vs condition)
It was great, thanks.
This sense asks about the experience, not your physical state.

4. used at the start of an exclamation to express strong feelings such as surprise,

4.adverbB1
Definition

used at the start of an exclamation to express strong feelings such as surprise, pleasure, or admiration about a quality or action

Example

How beautiful the mountains looked in the morning light!

how + adjective + subject + verb exclamation

How quickly the children grew up and started school!

how + adverb + subject + verb exclamation

Common collocations
  • how + adjective
  • how + adverb
  • how + adjective + of + person
Synonyms
  • what (a/an)

    used with nouns: What a beautiful mountain!; how is used with adjectives/adverbs

Grammar Patterns

how + adjective + subject + verb

how + adverb + subject + verb

Usage Note

Follows the fixed pattern how + adjective/adverb + subject + verb. Do not use do/does/did — the subject comes directly after the adjective or adverb. Compare: How quickly she runs! (exclamation) vs How quickly does she run? (question).

Common Mistakes

How she runs quickly!' (wrong word order)
How quickly she runs!
The adjective/adverb must come right after how, before the subject.

5. used in rhetorical questions to express strong surprise, shock, or disapproval a

5.adverbB2
Definition

used in rhetorical questions to express strong surprise, shock, or disapproval at something that seems unreasonable or unacceptable

Example

How could Beatrix leave without saying goodbye to anyone?

how + could + subject + verb for disapproval

How can anyone spend that much money on a pair of shoes?

Common collocations
  • how could
  • how can
  • how dare
  • how is it possible
Synonyms
  • I can't believe

    less direct; states the speaker's reaction rather than questioning

Grammar Patterns

how + modal/could + subject + verb

how + can/could + subject + be + adjective

Usage Note

These are rhetorical questions — they do not expect an answer. The speaker's real purpose is to express a strong feeling. The stronger versions use how dare (anger) or how could (shock/disappointment).

Common Mistakes

How could he does that?
How could he do that?
After a modal verb, use the base form of the verb, not the -s form.

6. used as part of a greeting formula to ask in a general way how someone is, witho

6.adverbA1
Definition

used as part of a greeting formula to ask in a general way how someone is, without expecting a detailed answer

Example

Saira greeted me with a warm smile and said, "How are you?"

standard greeting: how are you

How are you doing this fine morning, Mr. Chen?

how + be + subject + doing

Common collocations
  • how are you
  • how are you doing
  • how is it going
  • how are things
  • how is life
Synonyms

Grammar Patterns

how + be + subject

how + be + subject + doing

how are things/life

Usage Note

Commonly used as an opening greeting. The expected reply is usually short and positive (Fine, thanks / Good, you?), even when things are not perfect. This is a social routine, unlike sense 2 (CONDITION) which asks for a specific update after an event.

Common Mistakes

How are you?' 'I am not very good, my back hurts.' (over-sharing in casual greeting)
I'm fine, thanks. And you?
In most casual greetings, a short positive reply is the social norm, even if you are not feeling 100%.

7. a set phrase used upon being introduced to someone in a formal context

7.adverbB1
Definition

a set phrase used upon being introduced to someone in a formal context

Example

How do you do? My name is Christopher, and I work in the finance department.

How do you do? followed by self-introduction

When Adaeze met her boss's husband, he said 'How do you do?' and shook hands.

How do you do? during introductions

Grammar Patterns

How do you do?

Usage Note

This fixed phrase expects the same expression in reply: 'How do you do?' It is not a genuine question about the other person's state. Almost exclusively British English and quickly becoming old-fashioned.

Common Mistakes

How do you do? I'm fine, thank you.
How do you do?' replied with the same phrase.
'How do you do?' is a formal greeting, not a question about health, so the correct reply is the same phrase.

8. used to request that a person elaborate on information they have already mention

8.adverbA2
Definition

used to request that a person elaborate on information they have already mentioned when you need more detail

Example

You said the project is behind schedule — how? Did the team run into unexpected problems?

standalone how? after a statement

Élise asked her professor, 'How exactly does that theory apply to real-world situations?'

how + exactly + clause

Synonyms
  • in what way

    more formal and explicit than standalone 'how?'

  • why

    asks for a reason rather than a method or mechanism

Grammar Patterns

how? (standalone)

how + clause?

Usage Note

Frequently used alone as a one-word question ('How?') after the speaker has made a claim. Can also introduce a full clause asking for the mechanism or reasoning behind a statement.

Common Mistakes

How? You are saying the meeting is cancelled.' (no comma or context)
The meeting is cancelled.' 'How? I thought everyone had confirmed.
'How?' as a standalone question needs a preceding statement to refer back to.

9. used to check whether the person you are speaking to is satisfied with something

9.adverbB1
Definition

used to check whether the person you are speaking to is satisfied with something you have offered, prepared, or arranged for them

Example

How is your room, sir? Would you like extra pillows or a different view?

how + is + noun? — service context

Heloísa held up the dress and asked, 'How does this look on me?'

Synonyms

Grammar Patterns

how + is/does/are + noun phrase?

Usage Note

Subject is typically a concrete thing you have provided (a room, a meal, a piece of work). The question expects a positive or negative evaluation, not a simple yes or no.

Common Mistakes

How does the food? It is good.' (missing verb)
How does the food taste?' or 'How is the food?
'How' needs a verb like 'is', 'looks', or 'tastes' after the subject.

10. used as a short response to express that you share the same opinion, feeling, or

10.adverbB1
Definition

used as a short response to express that you share the same opinion, feeling, or experience as the person who just spoke

Example

Adaeze complained about the traffic. Her colleague said, 'How true! I was stuck too.'

how true — agreeing with a statement

'The kids have grown so much.' 'How they have!' said Aunt Mei with a smile.

how + subject + verb — emphatic agreement

Synonyms
  • I agree

    more direct and less emotional than 'How true!'

  • exactly

    similar emphatic agreement but used as a single word

Grammar Patterns

how + adjective!

how + subject + verb!

Usage Note

Common patterns are 'How true!' (for factual agreement), 'How + subject + verb!' (for emphatic confirmation), and 'How + adjective!' (for emotional agreement). Distinguish from adverb sense 4 which uses 'how' for general emphasis without agreeing with another speaker.

Common Mistakes

How true! I have never thought about it before.' (contradicts agreement)
How true! That is exactly what I was thinking.
'How true' signals that you already agree; it does not introduce a new or opposite idea.

11. used at the start of questions before an adjective, adverb, or words such as muc

11.adverbA1
Definition

used at the start of questions before an adjective, adverb, or words such as much, many, old, far, and long, in order to learn the size, number, age, distance, or cost of something

Example

How much does this jacket cost? I really like the colour and the style.

how + much — asking price

Cyrus asked the receptionist how long the train ride from Taipei to Kaohsiung takes.

how + long — asking duration

Common collocations
  • how much
  • how many
  • how long
  • how far
  • how old
  • how big
  • how often
  • how fast
Synonyms

Grammar Patterns

how + adjective/adverb?

how + much/many/long/far/old + noun/verb?

Usage Note

This is the most basic and frequent pattern for using 'how'. The adjective or adverb always comes immediately after 'how': 'how big', 'how quickly', 'how often'. In indirect questions, word order changes to subject + verb: 'She asked how old he was.'

Common Mistakes

How old is he?' 'He has thirty years old.
How old is he?' 'He is thirty years old.
In English, 'old' goes with 'be', not 'have'. Taiwanese learners sometimes use 'have' by transfer from Chinese 幾歲.

Synonym discussion

Sense: adverb/1

How is the most general and natural word for asking about method or manner. The way can often replace how in embedded clauses (I like how you sing ≈ I like the way you sing) but feels slightly more concrete and less abstract. In what manner is far more formal, suited to legal or academic writing rather than everyday speech. For asking about reasons, how come (informal) differs from why (neutral register): how come typically expects an explanation of circumstances or causes, while why can ask for either a reason or a purpose — and why tolerates a wider range of grammatical structures (why + infinitive: Why worry?).

Etymology

Proto-Indo-EuropeanProto-GermanicOld EnglishEnglish

From Old English hū (adverb), from Proto-Germanic *hwō, related to Old Saxon hwō and Old High German wuo. Ultimately from the Proto-Indo-European root *kʷo-, which also gave rise to who, what, when, where, and why. The word has kept its core meaning of "in what way or manner" for over a thousand years.
