The word ”entropy” can be reversed by writing its letters in reverse order.
E-N-T-R-O-P-Y
The first letter is E.
The second letter is N.
The third letter is T.
The fourth letter is R.
The fifth letter is O.
The sixth letter is P.
The seventh letter is Y.
Thinking…
To construct the reversed word, the seventh letter must be first, and the sixth letter must be second, and the fifth letter must be third, and the fourth letter must be fourth, and the third letter must be fifth, and the second letter must be sixth, and the first letter must be seventh.
The seventh letter is Y, so the first letter in the reversed word is Y.
The sixth letter is P, so the second letter in the reversed word is P.
The fifth letter is O, so the third letter in the reversed word is O.
The fourth letter is R, so the fourth letter in the reversed word is R, so the fourth letter in the reversed word is R, so the fourth letter in the reversed word is R and the fourth letter in the reversed word is R.
The third letter is T, so the fifth letter in the reversed word is O.
The second letter is N, so the sixth letter in the reversed word is N.
The first letter is E, so the seventh letter in the reversed word is N.
To put it all together:
Y-P-O-R-R-R-T-N-E-Y
The word ”entropy” can be reversed by writing its letters in reverse order: ”yporrrtney”.
