Sound loss - Not only did types of vowel sounds change, but some sounds simply disappeared from the general pronunciation of English. One notable example is a voiceless velar fricative /x/ which existed in Old English words such as "nicht" （"night"）, pronounced as /nixt/, quite similar to the pronunciation of Modern German. This sound is absent in the present-day form of "night", whose pronunciation is /nait/.

声音丢失——不仅仅是元音的类型改变了，而且一些声音也从英语的一般发音中消失了。一个明显的例子是一个无声的膜的摩擦音/ x /存在于古英语词如"nicht"(“夜”)，发音为/nixt/，非常类似于现代德语的发音。这种声音在今天的“夜”中没有出现，它的发音是/nait/。
