instantaneous和instant有什么区别?后缀aneous表示什么?

通过后缀aneous的来源就可以知道这两个词区别.
1640s (implied in instantaneously),formed in English from M.L.*instantaneus,from instantem (see instant (n.)) on model of spontaneous,simultaneous.
意思是说aneous来自spontaneous和simultaneous.
instantaneous侧重描述事件发生的突然性
instant侧重描述事件发生之快
两个例子对比：
1.他的第一反应是跑
His instantaneous response was to run.这个时候用instant就不如instantaneous合适.
2.他马上就反应过来然后跑了
His instant response was running away.这个时候用instant就比instantaneous合适.
