Reverse Word Order

In short Reversing word order flips the sequence of words while leaving each word spelled correctly, so "the quick brown fox" becomes "fox brown quick the". It is distinct from reversing characters, which would give "xof nworb kciuq eht" — the words themselves stay readable here, only their order changes. The everyday uses are small but real: turning "Surname Firstname" into "Firstname Surname" across a whole list, reversing a name order between conventions that put the family name first and those that put it last, and puzzles or word games. Working line by line rather than across the whole text is usually what you want for a list, so each line is reversed independently and the lines stay in place. Punctuation moves with the word it is attached to, which means a sentence reversed this way keeps its full stop on what is now the first word — that is a consequence of treating punctuation as part of the token, and it is worth a glance at the output rather than an assumption.
