The Knight moves one square along any rank or file in any direction and then moves 1 square diagonally away from its starting square.

The Knight moves from point to point (to the nearest square that is NOT along a file, rank or diagonal), and not along lines.
Otherwise, it couldn't jump.

I think he's asking how you would DESCRIBE a Knight move, not how to figure out the destination square.

The Knight moves from point to point (to the nearest square that is NOT along a file, rank or diagonal), and not along lines.
Otherwise, it couldn't jump.
So then technically it doesn’t jump, it goes around or through?
The chess-board is porous to Knight moves because they do not move along lines like all the other pieces do... effectively, they teleport.

I'm not sure how describing it as an "L" would be incorrect.
Point-to-point explains why "intervening" pieces and Pawns don't block the Knight move.
Describing the move as an L (which involves movement along files and ranks) means that you still need a SECOND rule about jumping over intervening pieces.
The Point-to-point explanation is more mathematically elegant, and therefore more "True".

“It may move to one of the squares nearest to that on which it stands but not on the same rank, file or diagonal.”
FIDE Handbook
A knight will land on the opposite color from where it is being moved and that square will be one square away.
Easy to visualize if you place the knight on a square and then a pawn on all eight potential landing squares, the pawns will form a circle. And the pawns will also be on the opposite color of the knight.
Makes for easy visualization over the board and whole lot less complicated than; One up and two over, or was it two up and one over? etc.
At least, that's the way I think about it. Its a visual thing for me.

An L pattern description is the Westernized version that completely butchers a proper description. To add insult to injury- the Knight now “jumps” over pieces, including the King! How moronic is that ?
The Knight travels through the squares - same as the other pieces and pawns.
One square along a rank or file and then 1 square diagonally away from its starting square. A combination of the two standard moves.

Perhaps the original idea behind its movement. There is the King and Queen. Both move rank or file or diagonal in any direction. The Rooks and Bishops are a limited version-Rooks ranks and files, Bishops only on the diagonals. Another piece is needed to fill the back ranks. The Knight is born - combines the rook and bishop move.

For example:

Also, the knight can jump over pieces, like this:
The white knight hops over the black pawn in this situation, while the black knight captures the white rook. Note that the knight captures pieces in the same way as it moves, and captures the piece that is on its landing square. If pieces are surrounding it, the knight is the only piece to be able to hop out. Like this:
and white promotes. (above position is fake)
