Translation Traps (for Russian speakers)
- Do not confuse with 'эксплант' (a direct loanword with identical meaning). The main trap is assuming it's a common word; it is highly specialized.
Common Mistakes
- Using 'explant' as a general synonym for 'explain' (homophone confusion).
- Using it outside of a biological context.
- Confusing verb and noun forms in sentence structure (e.g., 'We made an explant' vs. 'We will explant the tissue').
