Translation Traps (for Russian speakers)
- Avoid translating 'saline solution' as 'соляной раствор' in casual contexts where 'физиологический раствор' is the medical term. 'Saline' is not 'сельдерей' (celery).
Common Mistakes
- Mispronouncing as /səˈliːn/ or /ˈsæ.laɪn/. Using 'saline' as a verb (*to saline a wound*). Confusing with 'salient'.

FAQ
Frequently Asked Questions
In general terms, yes, but in medicine, 'saline' specifically refers to a sterile, isotonic solution of sodium chloride (0.9%), whereas 'salt water' is non-sterile and variable in concentration.
It is technically accurate but very formal. Words like 'salty', 'briny', or 'salted' are far more common in culinary contexts.
Sterile water has no salts. Saline contains sodium chloride at a concentration that matches bodily fluids, making it less likely to damage cells during medical procedures like IV infusion.
In British English: /ˈseɪ.laɪn/ (SAY-line). In American English: /ˈseɪˌliːn/ (SAY-leen). The second syllable is the main difference.
