duct
A duct is a tube or pipe that carries air, liquid, or other materials from one place to another.
Explanation at your level:
A duct is a tube. It carries air or water. You can see them in houses. They help keep rooms cool or warm. It is very useful.
A duct is a pipe or channel. It moves air in your house. It also moves liquid in your body. For example, you have tear ducts in your eyes.
In engineering, a duct is a passage for air or cables. In biology, it is a tube in the body. We often talk about 'air ducts' when discussing home heating systems.
The term duct is used to describe conduits for various substances. While mechanical ducts are common in architecture, biological ducts are essential for glandular functions, such as the secretion of enzymes.
Beyond its literal meaning, duct serves as a technical descriptor for any channelized transport system. Its usage spans from industrial HVAC design to complex physiological anatomy, reflecting the Latin root ducere, meaning 'to lead' or 'to guide' substances.
Etymologically, duct encapsulates the concept of guided movement. In advanced academic discourse, it is used to describe systemic pathways, whether in the context of urban infrastructure or the intricate vascular and glandular networks of the human body. It remains a precise, functional term in both scientific and technical lexicons.

- A duct is a tube for air or liquid.
- Common in homes and human bodies.
- Plural is ducts.
- Comes from Latin 'to lead'.
Think of a duct as a specialized highway for things that need to travel. Whether it is air moving through your house or fluids moving through your body, a duct provides the safe, enclosed path required for transport.
In your home, you might see metal vents on the ceiling; those are the ends of air ducts. They are vital for heating and cooling. In biology, your body is full of tiny ducts that move important chemicals around to keep you healthy.
The word duct comes from the Latin word ductus, which means 'a leading' or 'a conducting.' It is derived from the verb ducere, meaning 'to lead.'
This root is incredibly productive in English. You can see it in words like conduct, induct, and produce. Historically, it was used to describe water channels or aqueducts, evolving over centuries to include modern mechanical and biological meanings.
You will hear duct used most often in technical, construction, or medical contexts. It is a neutral, descriptive term rather than a slang word.
Common collocations include air duct, ventilation duct, and tear duct. When speaking about home maintenance, people often refer to 'duct cleaning' to improve air quality.
While duct itself isn't the core of many common idioms, it appears in phrases related to its function:
- Duct tape: A strong, versatile adhesive tape.
- Tear duct blocked: A medical condition causing watery eyes.
- Air duct system: The network of pathways in a building.
- Ductwork installation: The process of setting up these channels.
- Bile duct surgery: A specific medical procedure.
Duct is a countable noun. Its plural form is ducts. It is pronounced /dʌkt/ in both US and UK English, rhyming with bucked, plucked, and tucked.
It is often used with articles: 'The duct was blocked' or 'We need a new duct.' It functions as the subject or object in a sentence.
