vasopressin
C1Technical/Scientific/Medical
Definition
Meaning
A peptide hormone secreted by the pituitary gland that regulates water retention in the kidneys and constricts blood vessels.
In medical and biological contexts, it also refers to the synthetic form (arginine vasopressin) used as a medication to treat conditions like diabetes insipidus, septic shock, and cardiac arrest. It is sometimes referred to as antidiuretic hormone (ADH).
Linguistics
Semantic Notes
The term is highly domain-specific. In non-technical contexts, it is almost never used. Its primary semantic field is endocrinology and critical care medicine. It names a specific chemical substance with defined physiological functions.

Learning
Memory Aids
Mnemonic
Think 'Vessel Presser-in': It presses on (constricts) blood VESSELS and presses IN water retention.
Conceptual Metaphor
THE BODY IS A PLUMBING SYSTEM (vasopressin is a regulator of water pressure and pipe width).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'vasodilator' (вазодилататор), which has the opposite effect.
- The suffix '-pressin' relates to pressure, not depression or compression in a general sense.
- The Russian equivalent is often 'вазопрессин' or 'антидиуретический гормон' (АДГ). Ensure the correct term is used for the context.
Common Mistakes
- Mispronouncing it as 'vaso-PREH-sin' (stress is on 'press').
- Confusing it with oxytocin (another pituitary hormone).
- Using it as a general term for any blood pressure medication.
