记忆：affiliate 读起来像“阿菲利艾特”。想象阿菲利把自己的名字登记进社团名册，从此成为其会员或附属机构——记住“使加入、使隶属”。
语域：formal 常见场景：business、academic、organizational affiliate 作动词时通常用于正式或商务语境，表示“使隶属、使加入（某组织）”，比较常见于公司与机构关系的描述；在口语中较少使用，若表示“交往”则属于非正式且较罕见。
这些词作动词时，结尾的 -ate 都读作 /eɪt/，与 affiliate 的动词读音 /əˈfɪliˌeɪt/ 押韵。注意 affiliate 作名词时读 /əˈfɪliət/，结尾是 /ət/；同理，像 delicate /ˈdelɪkət/ 这类形容词的 -ate 也常读 /ət/，拼写相同但读音不同，需根据词性判断。
