Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with common 'яблоко' (apple). This is a distinct, specific fruit with no direct Russian equivalent. Periphrastic translation like 'южноафриканское колючее фруктовое дерево' may be needed.
- The hyphen is often retained in English, but the word is a single lexical unit.
Common Mistakes
- Misspelling as 'key apple'.
- Capitalising incorrectly (proper noun element 'Kei' but usually lowercased in compound).
- Using it as a general term for any apple-like fruit.
