Common Pitfalls
Translation Traps (for Russian speakers)

- In Russian, 'утюжить' is a direct verb for ironing clothes; in English it's simply 'to iron'.
- The adjective 'iron' meaning 'made of iron' (железный) is the same word, not a different one.
Common Mistakes
- Incorrect pronunciation: pronouncing the 'r' like in 'irony' (it is silent: /ˈaɪən/).
- Spelling error: 'iern' or 'iorn'.
- Using as a verb without an object: 'I need to iron' (correct) vs. 'I need to do the iron' (incorrect – should be 'do the ironing').
