Author/Opus: This is the 89th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the words into the grid (one letter per cell) so that they do not touch each other, not even diagonally, and so that they can be read in a straight line in a vertical or horizontal direction.

Then find a path that passes through every cell of the grid, starting with the first letter of the first word, passing through the words in order from their first letters to their last letters, and ending at the last letter of the last word.
