Enable is used especially with a person as object, in the phrase enable sb to do sth. Allow and permit can also be used in this structure, but usually with the meaning 'give sb permission to do sth'; in this meaning they are more often used with a thing as object, including in the phrase allow/permit sth to happen/be done. Permit is more formal than allow and is used especially in the fixed phrases if time permits and weather permitting.这些词的词义相同，但用法有些区别。enable尤后接sb作宾语，构成短语enable sb to do sth。allow和permit也可用于这种结构，但是通常意为“允许某人做某事”。因此表达“使能够”这个含义时，这两个词常常后接sth作宾语，构成短语allow/permit sth to happen/be done。permit较allow正式，尤其用于固定结构if time permits和weather permitting。
