语域：informal 常见场景：商务会议、政治场合、组织内部 bigwig 是较口语化的说法，通常用于非正式场合，指某个组织或领域中的要人或大亨，语气略带轻松或调侃。正式书面语中较少使用。
These words all end with the /ɪɡ/ sound and rhyme with the final syllable of bigwig (/ˈbɪɡˌwɪɡ/). Note that bigwig is literally 'big' + 'wig'. Be careful with the 'igh' spelling in lookalikes like high /haɪ/ and sign /saɪn/, which are pronounced with a long vowel and silent 'gh'. Also, pig /pɪɡ/ and pick /pɪk/ differ only in the final consonant.
