# Longest word with adjacent letters on a keyboard (without using any letters twice)

I know this question is very similar to GOTO 0's Longest word with adjacent letters on a keyboard, but all the answers to GOTO 0's question had many repeating letters. I need to find a word in this list that all the letters within are adjacent to the next on a QWERTY keyboard layout, that also only uses each letter once.

GOTO 0's keyboard for reference

 ┌───┬───┬───┬───┬───┬───┬───┬───┬───┬───┐
| Q | W | E | R | T | Y | U | I | O | P |
└─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┘
| A | S | D | F | G | H | J | K | L |
└─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴───┘
| Z | X | C | V | B | N | M |
└───┴───┴───┴───┴───┴───┴───┘

• Can you define adjacent in this context? For instance are diagonals allowed? – Beastly Gerbil Apr 20 '20 at 20:34
