adjective
British English

Think of LACTOSE (milk sugar) + -EAL (relating to). It's the 'milk-related' vessel.
Conceptual Metaphor
THE BODY IS A TRANSPORT SYSTEM (for the anatomical sense).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "лактационный" (lactational, relating to milk production). "Lacteal" is about transport/absorption, not secretion. The Russian anatomical equivalent is "млечный" (as in "млечный проток").
Common Mistakes
- Using it as a general synonym for 'dairy'.
- Pronouncing it as /leɪkˈtiː.əl/.
- Confusing it with 'lactate' (a salt or ester of lactic acid).

FAQ
Frequently Asked Questions
No, it is a rare, technical term used almost exclusively in medical and biological fields.
Not precisely. It describes things *related to* or *resembling* milk, especially in an anatomical context. You would not say 'lacteal milk'.
The word itself is primarily an adjective. The related noun for the anatomical structure is 'lacteal' (used as a noun, e.g., 'the lacteals') or 'lacteal vessel'.
Lacteals are a specific *type* of lymphatic vessel located in the small intestine, specialized for absorbing dietary fats. All lacteals are lymphatic vessels, but not all lymphatic vessels are lacteals.
