Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'поясничный' in non-anatomical contexts (e.g., 'поясничная записка' is an 'explanatory note', not a 'lumbar note').
- Direct translation of 'lumbar puncture' is 'люмбальная пункция', not a calque using 'поясничный'.
Common Mistakes
- Misspelling as 'lumber'.
- Using it as a noun to mean 'the back' (e.g., 'I hurt my lumbar' is non-standard; 'I hurt my lumbar region' is correct).
- Mispronouncing the 'b' as silent (it is /ˈlʌm.bɑː/, not /ˈlʌm.ɑː/).

FAQ
Frequently Asked Questions
It is almost exclusively used as an adjective (e.g., lumbar spine). Using it as a standalone noun (e.g., 'I have a pain in my lumbar') is considered non-standard; use 'lumbar region' instead.
A lumbar puncture (or spinal tap) is a medical procedure where a needle is inserted into the lower part of the spinal canal to collect cerebrospinal fluid for testing or to administer medication.
There are typically five lumbar vertebrae, labelled L1 to L5. They are the largest movable vertebrae in the spine.
Yes, but primarily in the context of ergonomics and design, such as 'lumbar support' in chairs and car seats. It remains a technical term even in these applications.
