ख़तरनाक (khatarnaak)

adjective A single-sense adjective meaning 'dangerous,' used for physical danger as well as figuratively for risky situations, people, or ideas.
Sense 1 : dangerous, risky, hazardous
adjective
Synonyms: ख़तरनाक (khatarnaak), जोखिम भरा (jokhim bharaa), भयानक (bhayaanak, can lean toward 'terrifying' rather than just 'risky')
Frequency: high
Cultural Note: You will hear ख़तरनाक (khatarnaak) applied very broadly in everyday Delhi speech -- not just to a dangerous road or animal, but to a fiercely competitive exam, a scarily fast driver, or even, admiringly, a brilliant chess move or a spicy dish. It carries a nice flexibility between literal danger and colloquial intensity, much like English 'wicked' or 'deadly' used loosely.
Common Mistakes: 1) Learners often reach for मुश्किल (mushkil, 'difficult') when they mean 'dangerous' -- मुश्किल (mushkil) is about difficulty, not risk to life or safety; keep ख़तरनाक (khatarnaak) for actual danger. 2) The nuqta under the ख़ (kh) is often dropped in casual writing (खतरनाक), which is fine in speech but worth noticing since it reflects the word's Persian-derived sound.
