B1 verb #16 よく出る 3分で読める

operate

To make a machine work or to perform a medical surgery.

Explanation at your level:

To operate means to make a machine work. If you turn on a light, you operate the switch. If you use a computer, you operate the keyboard. It is a very useful word for things that have buttons or levers.

You can use operate to talk about how things work in a business. For example, 'This shop operates from 9 AM to 5 PM.' It means that is the time the shop is open and doing work. You can also use it for machines, like 'He knows how to operate a tractor.'

At this level, you can use operate to talk about systems and organizations. 'The company operates in many countries.' It suggests a level of complexity. Also, remember the medical meaning: 'The doctor had to operate on his leg.' This is a common way to talk about surgery.

Operate is often used in formal or technical contexts. You might hear, 'The software operates on a cloud-based system.' It implies a specific way of functioning. It is more precise than just saying 'works.' Using this word makes your English sound more professional and accurate.

In advanced English, operate can be used figuratively to describe influence or hidden agendas. 'The group operates under the guise of a charity.' This suggests a subtle, perhaps deceptive way of functioning. It is also common in academic writing to describe how a theory or social system operates within a specific framework.

At the mastery level, consider the etymological roots of operate. It implies a 'work' that is intentional and often systemic. In literary or high-level political analysis, we might say, 'The mechanisms of power operate through language.' This highlights the word's ability to describe invisible, structural forces. It is a powerful verb for describing the 'how' of any complex entity.

  • Operate means to control a machine.
  • It also means to perform surgery.
  • Used in business for how things function.
  • Always use 'on' for medical surgery.

When you operate something, you are in the driver's seat. Whether it is a complex piece of heavy machinery at a construction site or just the remote control for your television, the word implies that you have the knowledge to make it function correctly.

Beyond machines, we use this word to describe how organizations or systems function. For example, a business might operate on a tight budget, meaning that is the way it conducts its daily affairs. It is a versatile verb that bridges the gap between mechanical control and abstract organizational behavior.

Finally, we cannot forget the medical sense. When a surgeon operates, they are performing a delicate, often life-saving procedure. It is a word that carries weight, suggesting precision, responsibility, and professional skill in every context it touches.

The word operate has deep roots in Latin. It comes from the verb operari, which simply means 'to work'. This Latin root is also the ancestor of the word 'opera', which is fitting since an opera is a massive, coordinated work of art.

Throughout the Middle Ages, the term evolved through Old French as operer before entering the English language in the 16th century. Initially, it was used in a very general sense to describe any kind of physical labor or action. Over time, the meaning narrowed to focus specifically on the management or control of systems.

By the 18th century, the medical usage became standard. It is fascinating to see how a word that once meant 'to toil in the fields' shifted to describe the high-tech, precise world of modern surgery and digital systems. Words are living things, and operate perfectly captures our human desire to control and fix the world around us.

You will hear operate used in both casual and highly technical settings. In casual conversation, you might say, 'Do you know how to operate this coffee machine?' It is a neutral term that fits perfectly in daily life.

In professional settings, it is a staple. Businesses often talk about how they operate in different markets, or how a specific department operates under new management. It sounds professional and competent.

Common collocations include phrases like 'operate machinery,' 'operate a business,' and 'operate under the assumption.' Notice how these collocations shift from physical objects to abstract concepts. Always remember that while 'use' is a synonym, 'operate' suggests a higher level of technical involvement or systemic control.

Idioms involving operate often relate to how people or systems behave. 1. Operate on a shoestring: To work with very little money. 2. Operate behind the scenes: To work secretly or without public attention. 3. Operate at full capacity: Working as hard or as fast as possible. 4. Operate in a vacuum: To work without considering external influences or feedback. 5. Operate on all cylinders: To perform at the highest possible level of efficiency.

The word operate is a regular verb. Its past tense and past participle form is operated, and its present participle is operating. It is typically a transitive verb when talking about machines, meaning it takes an object (e.g., 'He operates the crane').

Pronunciation varies slightly between regions. In the UK, it is often pronounced /ˈɒp.ər.eɪt/, while in the US, the 'r' is more pronounced, and the vowel sounds are slightly flatter. The stress is always on the first syllable: OP-er-ate.

Common rhymes include 'cooperate,' 'obliterate,' and 'deliberate.' Remember that the 'a' in the final syllable is usually a long 'a' sound, rhyming with 'gate' or 'late'.
