Pronunciation & Spelling
名词 converse 读 /ˈkɒnvɜːs/(英)或 /ˈkɑːnvɝːs/(美),重音在第一个音节。这些词都拼作 -verse,末尾都是 /vɜːs/(美式 /vɝːs/),但重音和元音不同。verse 是单音节;universe 虽然也重读第一个音节,但其第一个元音不同,因此与名词 converse 不严格押韵。inverse 作名词时美式常读 /ˈɪnvɜːs/,英式也可读 /ˌɪnˈvɜːs/。reverse 和 averse 重读 -verse,与动词 converse /kənˈvɜːs/ 押韵,但与名词 converse 不押韵;diverse 因元音不同,也不与名词 converse 押韵。
