"同字"在英语中可以用 "homophone" 来表示。

"Homophone" 是由希腊语 "homo-"(同一)和 "phone"(声音)组成的词,意思是发音相同但意义不同的词。例如,"grate" 可以表示 "刻痕" 或 "烤箱","knight" 可以表示 "骑士" 或 "晚上"。

一些英文例句:

"I couldn't tell the difference between their voices – they were homophones." (我分辨不出他们的声音——他们是同音字。)
"Many Engpsh speakers have trouble with the homophones 'there', 'their', and 'they're'." (许多英语使用者在使用同音字 'there','their' 和 'they're' 时会有困难。)
"The word 'pair' is a homophone of the word 'pear'." (单词 'pair' 是单词 'pear' 的同音字。)
