关于名词limit, limitation的区别，大概搜罗了一下网友的理解。 个人觉得如下三点讲得比较接地气。
其一：
A limit is something that is imposed (often externally).
A limitation is a shortcoming or incapability to achieve certain things.
其二：
A limit is a measurable quantity.
(Even in a phrase like 'limits of human endurance', the tacit assumption is that endurance can be measured)
A limitation is an attribute (or lack of one) denoting a limit to one's capabilty in achieving something.
其三：
Limit is for something you can exceed,
while limitation is for something you cannot exceed (or generally impossible to exceed).
综合起来就是：
limit：“强加的，可测量的，能被超越的”限制；
limitation：“本身的，属性的，不能被超越的”限制；
