electrolyte
C1Technical/Scientific, with common use in health/fitness contexts.
Definition
Meaning
A substance that conducts electricity when dissolved in water or molten, due to the movement of ions.
In medicine and nutrition, a mineral in the blood, urine, or bodily fluids that carries an electric charge, crucial for hydration and nerve/muscle function. In technology, a key component in batteries and fuel cells.
Linguistics
Semantic Notes
The core sense relates to the physical chemistry property of ionic conduction. The extended health sense is a metonymic shift, referring specifically to the ions themselves (e.g., sodium, potassium) that are dissolved in bodily fluids.

Learning
Memory Aids
Mnemonic
Think of an ELECTRicalLYTE (light) bulb that only lights up when the circuit is complete with a conducting solution.
Conceptual Metaphor
BODY IS A BATTERY (electrolytes are the 'charge' that keeps it running).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'электролит' for the health sense; in Russian, this primarily means 'battery acid'. Use 'минералы/ионы/соли' or the specific ion name (e.g., калий) in health contexts.
Common Mistakes
- Using 'electrolyte' as a countable noun for a single ion ('a sodium electrolyte' is wrong; it's 'a sodium ion' or 'an electrolyte containing sodium').
- Confusing 'electrolyte' (the substance/ion) with 'electrode' (the conductor).

FAQ
Frequently Asked Questions
No. Gatorade is a drink that *contains* electrolytes (like sodium and potassium ions). The electrolytes are the dissolved minerals themselves.
Pure water is a very poor electrolyte because it has few ions. Tap or mineral water is a weak electrolyte due to dissolved minerals.
An electrolyte is the ion-conducting substance (liquid or paste). An electrode is the solid conductor (e.g., metal rod) placed into the electrolyte to make electrical contact.
Yes. Hyperkalaemia (excess potassium) and hypernatraemia (excess sodium) are dangerous conditions caused by electrolyte imbalances, often from over-supplementation or kidney problems.
