Common Mistakes
3. used before a noun that is followed by extra information — such as a clause star
used before a noun that is followed by extra information — such as a clause starting with 'that' or 'who', or a phrase with a preposition — so the listener knows exactly which one is meant.

- the + noun + in
- the + noun + at
Grammar Patterns
the + noun + that/who clause
the + noun + prepositional phrase
Usage Note
Distinguish from sense 1: sense 1 relies on earlier mention or obvious context, while sense 3 relies on words that follow the noun to identify it.
Common Mistakes
4. used before a singular countable noun to talk about the whole class or type of t
used before a singular countable noun to talk about the whole class or type of that thing, not just one particular example.
The dolphin is one of the most intelligent animals found in the ocean.
the + singular noun = whole class or type

- the + singular countable noun (general class)
Grammar Patterns
the + singular countable noun = the whole type
Usage Note
This sense is only used with singular countable nouns. For plural nouns expressing a general idea, drop 'the' entirely: 'Dolphins are intelligent.' not 'The dolphins are intelligent.' (that would mean specific dolphins).
Common Mistakes
5. used before an adjective to create a noun phrase that refers to everyone or ever
used before an adjective to create a noun phrase that refers to everyone or everything that has that particular quality.
The government should do more to help the poor find affordable housing.
the + adjective = group of people with that quality
New technology is making it easier for the disabled to work from home.

- the rich
- the poor
- the elderly
- the young
- the disabled
- the unemployed
- the homeless
- the impossible
Grammar Patterns
the + adjective (referring to a group of people)
Usage Note
Common with human-describing adjectives: 'the rich', 'the poor', 'the elderly', 'the young', 'the disabled', 'the unemployed', 'the homeless'. Less commonly used with non-human adjectives ('the impossible', 'the unknown').
Common Mistakes
6. used before a family name in its plural form to refer to all the members of that
used before a family name in its plural form to refer to all the members of that family, or to a married couple sharing that name.

the + plural surname = whole family
The Garcias have lived in this small coastal town for more than thirty years.
Did you know that the Parkers are adopting a rescue dog from the local shelter?
Esme spotted the Nakamuras at the farmers' market yesterday morning.
- the + surname + -s
- the + surname + -es
Grammar Patterns
the + plural surname = the family or married couple
Usage Note
The family name must be in plural form, even though English surnames usually do not change for plural. Follow regular plural rules: add -s (the Smiths, the Wangs) or -es (the Joneses, the Garcias).
Common Mistakes
7. placed before a measure — of price, distance, weight, or time — to mean 'for eac
placed before a measure — of price, distance, weight, or time — to mean 'for each one of those units'. If peaches cost three dollars the kilo, that means the price is three dollars for every kilogram you buy.
A local mechanic charges sixty euros the hour for labour and basic parts.
the + unit of measurement = each / every
Fresh salmon at the market costs about twelve euros the kilogram this week.
In rural areas of Japan, taxis charge around two dollars the kilometre for long trips.

During the sale, the shop was selling cotton fabric at just eight pounds the metre.
- the hour
- the kilo
- the kilogram
- the litre
- the metre
- the square metre
- the day
- the week
Grammar Patterns
the + unit of measurement = each / every
Usage Note
In modern everyday English, 'a' or 'per' is far more common than 'the' in this sense: '€60 an hour' sounds much more natural than '€60 the hour'. Using 'the' here is characteristic of informal spoken British English and can sound slightly old-fashioned.
Common Mistakes
8. placed before an abstract noun — like patience, courage, energy, time, or money
placed before an abstract noun — like patience, courage, energy, time, or money — to indicate that someone has or lacks a sufficient amount of that quality to do something. The sentence is nearly always negative or a question.
I do not have the patience to wait another hour for the delayed train.
not have the + abstract noun + to-infinitive = lack sufficient amount
Min did not have the courage to tell her parents about the damaged car.
After a long day, Dario did not have the energy to cook dinner at home.
Does the young team really have the expertise to handle such a large engineering project?
Salma does not have the money to repair her car after the accident last month.
- the patience
- the courage
- the energy
- the money
- the time
- the expertise
- the stamina
- the skills
- enough
equivalent in meaning but follows the noun instead of preceding it: 'I have enough patience' vs 'I have the patience'
- sufficient
more formal; used in academic or professional writing: 'sufficient expertise'
Grammar Patterns
not have the + abstract noun + to-infinitive
have the + abstract noun + to-infinitive (in questions)
Usage Note
This sense is overwhelmingly used in negative statements or yes-no questions. A positive statement like 'I have the patience to wait' would usually be understood differently — as referring to a specific amount already discussed, not as a general statement of sufficiency.
Common Mistakes
9. placed before a word for a time period — like moment, day, week, year, or era —
placed before a word for a time period — like moment, day, week, year, or era — to point to the one happening now, rather than one in the past or future.

at the moment = now

- at the moment
- for the moment
- the present
- the present time
- the present situation
- the current year
- the season
Grammar Patterns
at the moment
for the moment
the present + noun
this + time unit (colloquial equivalent)
Usage Note
The most common fixed expression using this sense is 'at the moment' meaning 'right now'. Other combinations such as 'the present situation', 'the current year', or 'the day we live in' are less frequent but follow the same logic. Do not confuse 'at the moment' (now) with 'for a moment' (briefly).
Common Mistakes
10. used with strong emphasis on the word 'the' — shown in writing by italics or cap
used with strong emphasis on the word 'the' — shown in writing by italics or capital letters, and in speech by heavy stress — to indicate that the following person or thing is the most famous, important, fashionable, or desirable example of that kind.
I cannot believe I just met THE Elon Musk in the hotel lobby this morning!
THE + famous name = emphatic stress
For a special dinner, try THE restaurant in Paris with three Michelin stars.
In classical music, Yo-Yo Ma is widely considered THE cellist of our generation.
This is THE painting that every serious art critic in London is currently discussing.
For fashion lovers, THE shop in Milan is the historic boutique on Via della Spiga.
- THE + famous name
- THE + best/ultimate + noun
- THE + only + noun
- the one and only
a more emphatic phrase used to introduce a uniquely famous person: 'the one and only Elvis Presley'
- the ultimate
used for the best example of something: 'the ultimate restaurant in Paris'
Grammar Patterns
THE + noun/name (stressed for emphasis)
Usage Note
In writing, the emphasis on 'the' is shown by italicising or underlining it, or by writing it in all capital letters: 'the' → 'the' or 'THE'. In speech, the word is pronounced /ðiː/ (like 'thee') regardless of whether the next word starts with a consonant or vowel sound, and is given noticeably stronger stress than usual.
Common Mistakes
11. appears before each of two comparative words in a linked pair, revealing that as
appears before each of two comparative words in a linked pair, revealing that as one quality rises or falls, the other shifts by a matching amount.
The more you practise playing the piano, the better your skills will become over time.

- the more… the more…
- the more… the less…
- the less… the more…
- the sooner… the better…
- the longer… the more…
Grammar Patterns
the + comparative, the + comparative
Usage Note
Both halves of this structure require 'the' before a comparative form. Omitting 'the' from either half is a frequent error. The structure can take adjectives ('the happier'), adverbs ('the sooner'), or noun phrases containing comparatives ('the more people').
Common Mistakes
This structure shows that a change in one thing causes an equal change in another thing.
The more Sara practices piano, the better she plays.
The less sugar Diego eats, the healthier he feels.
