hypodermic needle
C1Technical/Medical, but widely understood in general contexts.
Definition
Meaning
A very thin, hollow needle attached to a syringe, designed to penetrate the skin (hypodermis) to inject substances into or withdraw them from the body.
In a broader, metaphorical sense, it can refer to something that pierces deeply or delivers something directly and potently. It is also a common synecdoche for the syringe-needle assembly used in medical injections.
Linguistics
Semantic Notes
The term specifically denotes the needle component, though it is often used to refer to the entire syringe-and-needle unit. The core concept combines the ideas of penetration ('hypodermic' = under the skin) and a precise, sharp instrument.
Dialectal Variation
British vs American Usage
Differences
No major lexical differences. Both use 'hypodermic needle'. 'Hypodermic syringe' is an equally common full term in both. Spelling follows respective norms (e.g., 'hypodermic' not 'hypodermique').
Connotations
Identical connotations of medical procedure, vaccination, drug use, and sharp precision.
Frequency
Frequency is similar, with slightly higher everyday usage in American media related to public health discussions (e.g., needle exchange programs).

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'подкожная игла' – while understood, the standard term is 'шприц' (syringe) or 'игла для шприца/инъекций'. The adjective 'hypodermic' is 'подкожный' or 'для подкожных инъекций'.
Common Mistakes
- Using 'hypodermic' to describe non-medical needles (e.g., sewing needles). Confusing 'hypodermic' with 'hyperdermic' (a common misspelling). Using it as a verb (e.g., 'He hypodermicked the patient' is incorrect).

FAQ
Frequently Asked Questions
No. A syringe is the whole device, which includes a barrel and plunger. The hypodermic needle is the sharp, hollow, pointed metal part that attaches to the syringe.
In its core medical sense, no. Its design is specifically for subcutaneous, intramuscular, or intravenous access. However, fine-gauge hypodermic needles are sometimes used in precise scientific or industrial applications for fluid transfer.
It comes from Greek: 'hypo-' meaning 'under' and 'derma' meaning 'skin'. Literally, it means 'under the skin'.
A hypodermic needle is solid metal and is removed after the injection. An IV catheter consists of a hollow needle (stylet) inside a plastic tube (cannula); the needle is removed, leaving the flexible cannula in the vein for longer-term fluid delivery.
