如果lack做名词，可不可以有for lack of ,for 与lack之间不要加冠词吗？为什么？

如果我想说：因为缺少是用for/because of/ lack of 还是for a lack of

lack是名词，用for不用加冠词吗?晕倒

lack
noun
[mass noun]the state of being without or not having enough of something
缺少，缺乏
the case was dismissed for lack of evidence.
因缺乏证据该案件被撤销。
there is no lack of entertainment aboard ship.

[in sing.]there is a lack of parking space in the town.

缺乏，缺少
the novel lacks imagination.
这部小说缺乏想像。
[no obj.]she lacks in patience.

Sam did not lack for friends.
萨姆并不缺少朋友。

这是lack用作名词时的用法。

是不加冠词的，在此lack 是不可数名词。for lack of

名词实际上有很多都不是严格可数或不可数的，在此不必深究。关于lack 还可以用 be lacking in =be short of

lack sth

Lack缺乏，没有 Lack+of＋名词： The plants died for lack of water. Lack+名词： We lack the strength to walk any further. 短语： be lacking:欠缺、缺： Money was lacking to complete the building. Be lacking in缺乏（某种品质、特点等）,不够： He is not lacking in intelligence. Lack for 缺（多用于否定句） She does not lack for friends.
