"The Road Not Taken" is a narrative poem by Robert Frost, first published in the August 1915 issue of the Atlantic Monthly, and later published as the first poem in the 1916 poetry collection, Mountain Interval. Its central theme is the divergence of paths, both literally and figuratively, although its interpretation is noted for being complex and potentially divergent. The first 1915 publication differs from the 1916 republication in Mountain Interval: In line 13, "marked" is replaced by "kept" and a dash replaces a comma in line 18. Source: Wikipedia (en)
