语域：formal 常见场景：medical records、obstetrics、official statistics 该词多用于医学、产科和正式统计场合，属正式用语；日常口语中较少单独使用。
The words birth and berth are homophones /bɜːrθ/. Mirth and girth rhyme with them (also /ɜːrθ/). In stillbirth, the ending -birth is pronounced /bɜːrθ/ too, but the stress falls on still-, so it is not a perfect rhyme with the single-syllable words. Do not confuse berth with birth; they sound the same but differ in spelling and meaning.
