Definition
Meaning

Linguistics

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid directly translating "ramus" as "рамус" — the word does not exist in Russian. The correct translation is "ветвь" (vetv') in an anatomical/biological context, or more specifically, the anatomical Latin term "ветвь (кость и т.д.)" is used.
- It is a false friend with the Russian word "рама" (rama - frame).
Common Mistakes
- Using it in a non-technical context.
- Pronouncing it as /ˈræ.məs/ (like 'ram' + 'us').
- Confusing it with 'radius' (a different bone in the forearm).
- Using it as a plural (the plural is 'rami', pronounced /ˈreɪ.maɪ/).
