disputed origin

The expression originates from the mechanics of cursive handwriting, where the dotting of the letter i and the crossing of the letter t are final actions performed after the hand has already completed the word. These minor additions are easily omitted by a writer in haste.

The phrase is probably a reference to the meticulous nature of such finishing touches. It suggests a level of precision where even the smallest strokes of the pen are accounted for, ensuring that a lapse in attention does not leave the text unfinished or the letters ambiguous.
