在英语中，后缀“-ly”有两个用途：一是用作副词的标志，最常见的是将形容词转化为副词 ，表示动作的方式、程度或频率，用于修饰动词、形容词或其他副词；一是用作形容词的标志，通常是将名词转化为形容词，表示“具有……性质的”，用于描述人或事物的特征。此外，后缀“-ly”也可加在一些形容词后，构成形容词。
后缀-ly
1. 后缀“-ly”用于形容词后，将其转化为副词，用来描述动作的方式或程度。quick→quickly（快速地）；slow→slowly（缓慢地）；wise→wisely（明智地）。
2. 后缀“-ly”用于名词后，将其转化为形容词：①表示“具有……性质或特点的”，friend→friendly（友好的）。②表示“每隔……时间的”，week→weekly（每周的）；year→yearly（每年的）。
3. 后缀“-ly”用于形容词后，词性不变，但含义发生质变。lone（单独的）→lonely（孤独的）；dead（死的）→ deadly（致命的）。
