outwardly 和 ostensibly 和 What word is more used in spoken English? 的差別在哪裡？如果不好說明，請提供一些例句。

I think they both mean very similar things. Outwardly means to appear to be something (only) from the outside, and similarly Ostensibly means to appear to be something that it is not really. I would say outwardly is much more likely to be used than Ostensibly. Many people in England wouldn't know what Ostensibly means.
