Verb / Noun A2 — Elementary /wɜːk/

Work — Definition, Examples & Usage

One of the most common words in English — used as both a verb and a noun to describe effort, employment, and activity.

Quick Definition

Work (verb) — to do a job or task; to use effort or energy to achieve something; (of a machine or plan) to function or operate correctly.

Work (noun) — the activity of doing a job or task; employment; a task or project that requires effort; a literary or artistic creation.

What Does Work Mean?

Work is one of the most fundamental words in English, appearing among the thousand most frequently used words in the language. It comes from Old English weorc, which has Germanic origins and ultimately traces back to the Proto-Indo-European root *werg- meaning "to do". This ancient root also produced the Greek ergon (work, action), giving modern English words such as energy, organ, and surgery.

As a verb, work has three main senses: (1) to be employed or to do a job ("She works as a nurse"); (2) to put effort into a task ("We worked all weekend on the report"); and (3) to function or operate ("The heating isn't working"). The third sense is especially useful in everyday conversation and often catches learners by surprise.

As a noun, work is usually uncountable and refers to employment, the act of labouring, or a body of tasks. It becomes countable only in specific contexts such as literary or artistic productions ("the works of Shakespeare") or industrial facilities ("ironworks", "gasworks").

Usage Notes

Key Points for Learners

  • No article with "work" as a place: Say "go to work", "at work", "start work" — never "go to the work" or "at a work".
  • Work vs job: Work is uncountable and refers to activity or employment in general. Job is countable and refers to a specific paid position. "I need a job" and "I need work" are both correct, but "I need a work" is wrong.
  • Work meaning "to function": "Does the printer work?" / "The plan isn't working." This sense is extremely common in British English and must be learnt alongside the employment sense.
  • Work in compound nouns: English creates many compounds — homework, framework, network, groundwork, workload, workplace, workforce. These are all single words and should not be written as two separate words.
  • Works (plural noun): Use works to refer to literary or artistic productions ("Collected Works"), construction activity ("roadworks"), or an industrial facility ("steelworks").

Frequently Asked Questions about “work”

What does work mean in English?
As a verb, work means to do a job, task, or activity that requires effort: 'She works as a teacher.' As a noun, work refers to the activity itself ('Work starts at nine.'), a job or occupation ('I am looking for work.'), or a specific task or project ('We have a lot of work to do.'). The exact meaning depends on context.
Is work a verb or a noun?
Work is both a verb and a noun. As a verb: 'He works in finance.' As a noun: 'The work was exhausting.' This dual function makes it one of the most flexible words in English. In academic and professional writing, the noun form is especially common in phrases such as 'work in progress' and 'teamwork'.
Is work countable or uncountable?
As a noun, work is usually uncountable: 'I have a lot of work to do' (NOT 'a lot of works'). However, it becomes countable in some specific contexts: literary or artistic works ('the complete works of Shakespeare'), engineering or construction ('roadworks', 'public works'), and the expression 'the works' (meaning everything). Avoid saying 'a work' when you mean a job or task.
What is the difference between work and job?
Work (uncountable noun) refers to the general activity or effort involved in doing something: 'I enjoy my work.' Job (countable noun) refers to a specific paid position: 'She got a new job.' You can say 'I am looking for work' or 'I am looking for a job', but 'I am looking for a work' is incorrect. Both can describe employment, but job is always countable and work is usually not.
What common collocations use the word work?
Common verb collocations include: go to work, start work, finish work, look for work, and carry out work. Common adjective collocations include: hard work, teamwork, part-time work, full-time work, and voluntary work. In compound nouns you find: homework, framework, network, workload, and workplace. These collocations are essential for natural-sounding English.
How do you use work in a sentence?
As a verb: 'She works from home on Fridays.' 'The plan worked perfectly.' As a noun: 'He has been out of work for six months.' 'The restoration work took three years.' Remember that the verb work can also mean 'to function or operate': 'The lift is not working.' This third meaning is very common in everyday English.
What is the difference between work and works?
'Works' as a third-person singular verb: 'He works hard.' 'Works' as a plural noun refers to literary or artistic productions ('the collected works of Dickens'), construction ('roadworks ahead'), or a factory ('the steelworks'). In most everyday contexts, the uncountable noun is 'work' with no -s: 'There is a lot of work to do.'
What is the etymology of the word work?
Work comes from Old English 'weorc' or 'worc', meaning 'something done, deed, action, business, military fortification'. This traces back to Proto-Germanic '*werkan' and ultimately to the Proto-Indo-European root '*werg-' meaning 'to do'. The same root gives us words such as 'organ', 'energy', and 'surgery' in English via Greek and Latin.
What are common mistakes with the word work?
The most common mistakes are: (1) using work as a countable noun — 'I have many works to do' should be 'I have a lot of work to do'; (2) adding an article — 'I go to the work' should be 'I go to work'; (3) confusing work with job — 'I need a work' should be 'I need work' or 'I need a job'. All three errors are extremely common among ESL learners.
