Translation Traps (for Russian speakers)
- Avoid literal translation with 'imperforable' or 'imperforative'. The Russian equivalent is often 'неперфорированный' or descriptive like 'без отверстия'.
Common Mistakes
- Confusing with 'impervious' (not allowing passage through). 'Imperforate' describes the physical absence of a hole, not resistance to fluids.
- Mispronouncing as /ɪmˈpɔːfəreɪt/.
- Using as a verb (e.g., 'to imperforate').
