Discuss the significance of the title'road not taken'. would it have been more appropriate to use the title'road taken'?can u just give a brief...

Frost's "The Road Not Taken" is a lighthearted look and revisionism.  The speaker in the poem chooses one path for no real reason, since both of the paths are actually about the same.  Notice in the poem that there is no real difference between the two paths.

The speaker imagines himself in years to come, pretending there was a difference, and telling a yarn or white lie for the sake of entertainment.  He imagines himself making up a story about how he took the less-traveled path and that made all the difference. 

Therefore, since the poem deals with making up a story about the road not taken, it wouldn't make sense to call the poem "The Road Taken."
