A phonological rule that makes one sound similar to a neighboring one by copying one of its phonetic features. For example, the /i:/ sound in /bi:n/ is to some extent nasalized because it is assimilated by the nasal sound /n/ that follows it immediately.
同化规则是一种音系规则，它通过复制音标特征，使一个声音与它相邻的音标相似。例如，/i:/ 在/bi:n/中发音时，某种程度上是被鼻化的，因为它被紧接在它后面的鼻音/n/同化了。
