duct
B2Formal to Neutral; common in technical, medical, engineering, and construction contexts.
Definition
Meaning
A tube, channel, or pipe that carries something (air, liquid, cables, etc.) from one place to another.
A vessel in the body for conveying secretions or other fluids (e.g., tear duct); can also refer metaphorically to a conduit for ideas or emotions.
Linguistics
Semantic Notes
Primarily a countable noun. Its most frequent use is in technical domains. As a verb, it is highly specialised (engineering).
Dialectal Variation
British vs American Usage
Differences
Spelling and pronunciation are largely identical. The verb 'to duct' (to channel through a duct) is very rare in both varieties.
Connotations
Identical. Strongly associated with heating/ventilation (HVAC), anatomy, and engineering.
Frequency
Slightly more common in AmE due to widespread central air conditioning systems ('air duct'), but very common in both.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'duct' (проток) and 'duck' (утка) in pronunciation.
- The Russian 'тракт' (tract) is a broader term; 'duct' is a specific, often man-made or anatomical, tube.
Common Mistakes
- Misspelling as 'duck'.
- Using uncountably (e.g., 'made of duct') instead of 'ductwork'.
- Confusing 'duct' (channel) with 'dock' (port).

Frequently Asked Questions
A 'pipe' is typically for liquids/gases under pressure (e.g., water pipe). A 'duct' is often larger, for air flow or protected cables, and may not be sealed under high pressure.
Yes, but it's highly technical (engineering/construction). It means 'to convey through or enclose in a duct' (e.g., 'The wires are ducted in plastic').
Yes. It was originally developed during WWII as a waterproof sealing tape for ammunition cases. After the war, it was marketed for sealing heating and air conditioning ducts, hence the name, though it is not typically suitable for modern metal ducts.
Not many. 'Duct tape and dreams' is an informal AmE phrase suggesting a solution held together by improvisation and hope. The more common set phrase is simply 'duct tape'.
