语域：mixed 常见场景：名词：新闻/灾害报道、动词：正式写作/文学 havoc 作名词表示‘大破坏’，多与 wreak/cause 等搭配；作动词表示‘严重破坏’，多用于正式或文学文体。语境不同，语气可从中性到正式，请根据写作场合选择。
No common words rhyme exactly with /ˈhævək/. 'hammock' and 'paddock' are close: they share /æ/ and final /ək/, but the consonant after the stressed vowel differs (/m/ or /d/ vs /v/). 'block', 'clock', 'shock' and 'stock' are spelling lookalikes ending in -ock; they are one-syllable /ɒk/ words, so do not use their vowel for 'havoc'.
