Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general verbs for 'burst' or 'explode' (like лопнуть, взорваться). It is a specific biological process. The Russian equivalent is often 'раскрываться' or 'зреть (о плодах)' in botanical contexts.
Common Mistakes
- Using it as a transitive verb (e.g., 'The sun dehisced the pod' - incorrect).
- Confusing it with 'desiccate' (to dry out).
