Flip the order of the words in each line, so the last word comes first. Different from reversing the letters.
Reversing text flips every character, so 'cat' becomes 'tac'. This tool keeps each word spelled normally but reverses their order, so 'the big cat' becomes 'cat big the'.
Yes. Each line is reversed on its own, and blank lines and line breaks are kept, so the overall shape of your text stays the same.
Words are separated by single spaces in the output. Leading, trailing and repeated spaces inside a line are collapsed to keep the result clean.
