Examples
By CEFR Level
- The doctor gave me medicine for the infection.
- I have to take an antibiotic called nitrofurantoin for a week.

Learning
Memory Aids
Mnemonic
Think: 'NITRO' (like explosive against bacteria) + 'FURAN' (chemical ring) + 'TOIN' (a common suffix for drugs like phenytoin). It fights bacteria in the urinary tract.
Conceptual Metaphor
A targeted cleaner/scavenger for the urinary system.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate component parts ('nitro', 'furan'). It is a fixed internationalism: 'нитрофурантоин'.

Common Mistakes
- Mispronouncing as 'nitro-furan-toin' (correct: 'nitro-fyu-ran-toin').
- Misspelling as 'nitrofuratonin' or 'nitrofurontoin'.
- Using it as a general term for any antibiotic.
